- ANNOKEY
-
specifies that annotation requested with the ANNOTATE=
option is to be applied only to the key cell.
By default, annotation is applied to all of the cells.
Use the CLASSKEY= option to specify the key cell.
- ANNOTATE=SAS-data-set
- ANNO=SAS-data-set
-
specifies an input data set containing annotate variables
as described in
SAS/GRAPH Software: Reference.
You can use this data set to add features to the
comparative histogram. The ANNOTATE= data set you specify
in the COMPHISTOGRAM statement is used for all plots
created by the statement. You can also specify an
ANNOTATE= data set in the PROC CAPABILITY statement to
enhance all plots created by
the procedure; for more information, see
"ANNOTATE= Data Sets" .
- BARWIDTH=value
-
specifies the width of the histogram bars in screen percent units.
- C=value-list | MISE
-
specifies the standardized bandwidth parameter c
for kernel density estimates requested with the KERNEL
option. You can specify up to five values to display
multiple estimates in each cell.
You can also specify the keyword MISE to request the bandwidth
parameter that minimizes the estimated mean integrated square
error (MISE). For example, consider the following statements
(for more information, see "Kernel Density Estimates" ):
proc capability;
comphist length / class=batch kernel(c = 0.5 1.0 mise);
run;
The KERNEL option displays three density estimates.
The first two have standardized bandwidths of 0.5 and
1.0, respectively. The third has a bandwidth parameter
that minimizes the MISE. You can also use the C= and K=
options (K= specifies kernel type) to display multiple
estimates. For example, consider the following statements:
proc capability;
comphist length / class = batch
kernel(c = 0.75 k = normal triangular);
run;
Here two estimates are displayed. The first uses a normal
kernel and bandwidth parameter of 0.75, and the second uses
a triangular kernel and a bandwidth parameter of 0.75. In
general, if more kernel types are specified than bandwidth
parameters, the last bandwidth parameter in the list will
be repeated for the remaining estimates. Likewise, if more
bandwidth parameters are specified than kernel types, the
last kernel type will be repeated for the remaining estimates.
The default is MISE.
- CAXIS=color
- CAXES=color
- CA=color
-
specifies the color for the axes, tick marks, and target line.
The default is the first color in the device color list.
- CBARLINE=color
-
specifies the color of the outline of the histogram bars.
This option overrides the C= option in the SYMBOL1 statement.
The default is the first color in the device color list.
- CFILL=color
-
specifies a color used to fill the bars of the
histograms (or the areas under a fitted curve if you
also specify the FILL option).
See the entry for the FILL option for additional details.
See Output 3.1.1 and Example 3.2
for examples. Refer to SAS/GRAPH Software: Reference
for a list of colors. By default, bars
and curve areas are not filled.
- CFRAME=color
-
specifies the color for the area enclosed by the axes and the
frame. This area is not filled by default. The CFRAME=
option cannot be used with the NOFRAME option,
the CTILES= option, or the variable _CTILE_ in a CLASSSPEC=
data set.
- CFRAMENLEG=color | EMPTY
-
specifies that the legend requested with the NLEGEND option
(or the variable _TILELB_ in a CLASSSPEC= data set)
is to be framed and that the frame is to be filled
with the color indicated. If you specify CFRAMENLEG=EMPTY,
a frame is drawn but not filled with a color.
- CFRAMESIDE=color
-
specifies the color for filling the frame area for
the row labels displayed along the left side of
a comparative histogram requested with the CLASS= option.
This color is also used to fill the frame area for the
label of the corresponding CLASS= variable (if a label
is associated with the variable.)
See Output 3.2.1 for an example.
By default, these areas are not filled.
- CFRAMETOP=color
-
specifies the color for filling the frame area for
the column labels displayed across the top of
a comparative histogram requested with the CLASS= option.
This color is also used to fill the frame area for the
label of the corresponding CLASS= variable (if a label
is associated with the variable.) See Output 3.2.1
for an example.
By default, these areas are not filled.
- CGRID=color
-
specifies the color for grid lines requested with the GRID
option. The default is the first color in the device color
list. If you use CGRID=, you do not need to specify the
GRID option.
- CHREF=color
-
specifies the color for lines requested with the HREF=option.
The default is the first color in the device color
list.
- CLASS=variable
- CLASS=(variable1 variable2)
-
specifies that a comparative histogram is to be created
using the levels of the variables (also referred to
as class-variables or classification variables).
If you specify a single variable,
a one-way comparative histogram is created. The observations
in the input data set are sorted by the formatted values (levels) of
the variable. A separate histogram is created for the
process variable values in each level, and these component
histograms are arranged in an array to form the comparative
histogram. Uniform horizontal and vertical axes are used to
facilitate comparisons. For an example, see Figure 3.2.
If you specify two classification variables, a two-way
comparative histogram is created. The observations in
the input data set are cross-classified according to the
values (levels) of these variables. A separate histogram
is created for the process variable values in each cell
of the cross-classification, and these component histograms
are arranged in a matrix to form the comparative
histogram. The levels of variable1 are used to
label the rows of the matrix, and the levels of
variable2 are used to label the columns of the matrix.
Uniform horizontal and vertical axes are used to facilitate
comparisons. For an example,
see Output 3.2.1.
Classification variables can be numeric or character,
and the length of a character variable cannot exceed 16.
Formatted values
are used to determine the levels. You can
specify whether missing values are to be treated as a
level with the MISSING1 and MISSING2 options.
If a label is associated with a classification variable,
the label is displayed on the comparative histogram.
The variable label is displayed parallel to the column
(or row) labels. For an example, see Figure 3.2.
- CLASSKEY='value'
- CLASSKEY=('value1' 'value2')
-
specifies the key cell in a comparative histogram
requested with the CLASS= option. The bin size and
midpoints are first determined for the key cell, and
then the midpoint list is extended to accommodate the
data ranges for the remaining cells. Thus, the choice
of the key cell determines the uniform horizontal axis
used for all cells.
If you specify CLASS=variable, you can specify
CLASSKEY='value' to identify the key cell as
the level for which variable is equal to value.
The value can have up to 16 characters, and you
must specify a formatted value.
By default, the levels are sorted in the order determined
by the ORDER1= option, and the key cell is the level that
occurs first in this order. The cells are displayed in
this order from top to bottom (or left to right),
and, consequently, the key cell is displayed at the top or at
the left. If you specify a different key cell with the
CLASSKEY= option, this cell is displayed at the top
or at the left unless you also specify the NOKEYMOVE option.
If you specify CLASS=(variable1 variable2), you can specify
CLASSKEY=('value1' 'value2') to identify the key cell as the
level for which variable1 is equal to value1 and
variable2 is equal to value2. Here, value1
and value2 must be formatted values, and they must be
enclosed in quotes. For an example of the CLASSKEY= option
with a two-way comparative histogram, see Output 3.2.1.
By default, the levels of variable1
are sorted in the order determined by the ORDER1= option, and
within each of these levels, the levels of variable2 are
sorted in the order determined by the ORDER2= option.
The default key cell is the combination of levels of variable1
and variable2 that occurs first in this order. The cells
are displayed in order of variable1 from top to bottom
and in order of variable2 from left to right. Consequently,
the default key cell is displayed in the upper left corner.
If you specify a different key cell with the
CLASSKEY= option, this cell is displayed in the upper left
corner unless you also specify the NOKEYMOVE option.
- CLASSSPEC=SAS-data-set
- CLASSSPECS=SAS-data-set
-
specifies a data set that provides distinct specification
limits for each cell, as
well as a color, legend, and label for the
corresponding tile. The following table lists the
variables that are read from a CLASSSPECS= data set:
|
Variable Name
|
Description
|
| BY variables | subsets the data set |
| Classification variables | specifies the structure of the comparative
histogram |
| _VAR_ | specifies name of process variable (must be
character variable of length 8) |
| _LSL_ | specifies lower specification limit for tile |
| _TARGET_ | specifies target value for tile |
| _USL_ | specifies upper specification limit for tile |
| _CTILE_ | specifies background color for tiles (must be
character variable of length 8) |
| _TILELG_ | specifies text displayed in color tile legend
at bottom of comparative histogram (character
variable of length not greater than 16) |
| _TILELB_ | specifies text displayed in corner of each tile
(character variable of length not greater than 16) |
If you specify a CLASSSPEC= data set, you cannot use
the SPEC statement or a SPEC= data set. If
you use a BY statement, the CLASSSPEC= data set must
contain one observation for each unique combination of
process and classification variables within each BY
group. See Example 3.1 for
an example of a CLASSSPECS= data set.
Also note that
- you can suppress the background color for a tile by
assigning the value EMPTY or a blank value
to the variable _CTILE_
- you can use the NLEGENDPOS= option to specify the
corner of the tile in which the
_TILELB_ label is displayed.
You can frame the label with the CFRAMENLEG= option.
- you cannot use the variable _TILELG_ unless you specify
the variable _CTILE_
- the variable _TILELB_ takes precedence over
the NLEGEND option
- COLOR=color
-
specifies the color of the normal density curve or
the kernel density estimate curve. Enclose the COLOR= option
in parentheses after the NORMAL option or the KERNEL option.
See Output 3.1.1 for an example.
- CPROP=color
-
specifies the color for a horizontal bar
whose length (relative to the width of the tile)
indicates the proportion of the total frequency
that is represented by the corresponding cell.
For an example, see Figure 3.3.
Empty bars are displayed if you specify
CPROP=EMPTY.
By default, bars are not displayed.
- CTEXT=color
-
- CT=color
- specifies the color for tick mark labels and axis labels.
The default is the color specified for the CTEXT=
option in the most recent GOPTIONS statement.
- CVREF=color
-
specifies the color for lines requested with the VREF= option.
The default is the first color in the device color
list.
- DESCRIPTION='string'
-
- DES='string'
- specifies a description, up to 40 characters,
that appears in the PROC GREPLAY master menu. The default
is the variable name.
- FILL
-
fills areas under a fitted density curve
with colors and patterns. Enclose the FILL option
in parentheses after the keyword NORMAL or KERNEL.
Depending on the area to be filled
(outside or between the specification limits),
you can specify the color and pattern with
options in the SPEC statement and the COMPHISTOGRAM statement,
as summarized in the following table:
|
Area Under Curve
|
Statement
|
Option
|
| between specification | COMPHIST | CFILL=color |
| limits | COMPHIST | PFILL=pattern |
| left of lower | SPEC | CLEFT=color |
| specification limit | SPEC | PLEFT=pattern |
| right of upper | SPEC | CRIGHT=color |
| specification limit | SPEC | PRIGHT=pattern |
If you do not display specification limits, you can use
the CFILL= and PFILL= options to specify the color and pattern
for the entire area under the curve.
Solid fills are used by default if patterns are not specified.
You can specify the FILL option with only one fitted curve.
For an example, see Output 3.1.1.
Refer to SAS/GRAPH Software: Reference
for a list of available patterns and colors.
If you do not specify the FILL option but you do specify
the options in the
preceding table, the colors and patterns are applied to the
corresponding areas under the histogram.
- FONT=font
-
specifies a software font for text used outside the
framed areas of a comparative histogram (labels for
axes, tick marks, and so forth). This font takes
precedence over the FTEXT= font specified in a
GOPTIONS statement. Refer to SAS/GRAPH
Software: Reference for a list of fonts.
- GRID
-
adds a grid to the comparative histogram.
Grid lines are horizontal lines positioned at major
tick marks on the vertical axis.
- HEIGHT=value
-
specifies the height in percent screen units of text
for axis labels, tick mark labels, and legends.
The HEIGHT= option
takes precedence over
the HTEXT= option in the GOPTIONS statement.
- HOFFSET=value
-
specifies the offset in percent screen units at both ends
of the horizontal axis. Specify HOFFSET=0 to eliminate
the default offset.
- HREF=value-list
-
draws reference lines perpendicular to the horizontal
axis at the values specified. For an illustration,
see Output 4.1.1.
- HREFLABELS='label1'...'labeln'
- HREFLABEL='label1'...'labeln'
- HREFLAB='label1'...'labeln'
-
specifies labels for the lines requested with the option. The number of labels must equal the number of
lines. Enclose the labels in quotes. Labels can be up
to 16 characters. For an illustration,
see Output 4.1.1.
- HREFLABPOS=n
-
specifies the vertical position of HREFLABELS=
labels as follows: 1 positions the labels along the top
of the histogram; 2 staggers the labels from top to bottom;
3 positions the labels along the bottom. The default is 1.
- INFONT=font
-
specifies a software font for text used inside the framed
areas of the comparative histogram (such as sample size
legends). The INFONT= option takes precedence over the FTEXT=
option in the GOPTIONS statement. Refer to SAS/GRAPH
Software: Reference for a list of fonts.
- INHEIGHT=value
-
specifies the height in percent screen units of text used
inside the framed areas of the comparative histogram (such
as sample size legends). The default height is the height you
specify with the HEIGHT= option. If you do not specify the HEIGHT=
option, the default height is the height you specify with the
HTEXT= option in the GOPTIONS statement.
- INTERTILE=value
-
specifies the distance in horizontal percent screen units
between tiles. For an example, see Figure 3.3.
By default, the tiles are contiguous.
- K=NORMAL | TRIANGULAR | QUADRATIC
-
specifies the type of kernel (normal, triangular, or quadratic)
used to compute kernel density estimates requested with the
KERNEL option. Enclose the K= option in parentheses after
the keyword KERNEL. You can specify a single type or a list of
types. If you specify more estimates than types, the last kernel
type in the list is used for the remaining estimates.
By default, a normal kernel is used.
- KERNEL<( kernel-options )>
-
requests a kernel density estimate for each
cell of the comparative histogram. You can specify
the kernel-options described in the following table:
| FILL | specifies that the area under the curve
is to be filled |
| COLOR= | specifies the color of the curve |
| L= | specifies the line style for the curve |
| W= | specifies the width of the curve |
| K= | specifies the type of kernel |
| C= | specifies the smoothing parameter |
See Output 3.1.1 for
an example.
By default, the estimate is based on the AMISE method.
For more information, see "Kernel Density Estimates" .
- L=linetype
-
specifies the line type for a normal or kernel density estimate
curve. Enclose the L= option in parentheses after the NORMAL
option or the KERNEL option. If you use the L= option with the
KERNEL option, you can specify a single line type or a list of
line types. Refer to SAS/GRAPH Software: Reference
for a list of available line types. The default is 1, which
produces a solid line.
- LGRID=n
-
specifies the line type for the grid requested with the GRID
option. If you use the LGRID= option, you do not need to
specify the GRID option. The default is 1, which produces
a solid line.
- LHREF=n
-
- LH=n
- specifies the line type for lines requested with the option. The default is 2, which produces a dashed line.
- LVREF=n
-
- LV=n
- specifies the line type for lines requested with the VREF=
option. The default is 2, which produces a dashed line.
- MAXNBIN=n
-
specifies the maximum number of bins to be displayed.
This option is useful in situations where the scales or
ranges of the data distributions differ greatly from
cell to cell.
By default, the bin size and midpoints
are determined for the key cell, and then the midpoint
list is extended to accommodate the data ranges for the
remaining cells. However, if the cell scales differ
considerably, the resulting number of bins may be so
great that each cell histogram is scaled into a narrow
region. By limiting the number of bins with the
MAXNBIN= option, you can narrow the window about the
data distribution in the key cell. Note that the
MAXNBIN= option provides an alternative to the
MAXSIGMAS= option.
- MAXSIGMAS=value
- limits the number of bins to be displayed to a range
of value standard deviations (of the data in the
key cell) above and below the mean of the data in the
key cell. This option is useful in situations where
the scales or ranges of the data distributions differ
greatly from cell to cell. By default, the bin size and
midpoints are determined for the key cell, and then the
midpoint list is extended to accommodate the data ranges
for the remaining cells. If the cell scales differ
considerably, however, the resulting number of bins may
be so great that each cell histogram is scaled into a
narrow region. By limiting the number of bins with the
MAXSIGMAS= option, you narrow the window about the data
distribution in the key cell. Note that the MAXSIGMAS=
option provides an alternative to the MAXNBIN= option.
- MIDPOINTS=value-list | KEY | UNIFORM
-
specifies how midpoints are determined for the bins in
the comparative histogram.
The method you specify is used for all process variables
analyzed with the COMPHISTOGRAM statement.
If you specify MIDPOINTS=value-list, the
values must be listed in increasing order
and must be evenly spaced. The difference between
consecutive midpoints is used as the width of the
histogram bars. If the range of the values
does not cover the range of the data as well as any
specification limits (LSL and USL) that are given,
the list is extended in either direction as necessary.
See Example 3.1 for an
illustration.
If you specify MIDPOINTS=KEY, the procedure first
determines the midpoints for the data in the key cell.
The initial number of midpoints is based on the number
of observations in the key cell using the method of
Terrell and Scott (1985). The midpoint list for the
key cell is then extended in either direction as
necessary until it spans the data in the remaining cells.
If you specify MIDPOINTS=UNIFORM, the procedure
determines the midpoints using all the observations
as if there were no cells. In other words, the number
of midpoints is based on the total sample size using
the method of Terrell and Scott (1985).
By default, MIDPOINTS=KEY. However, if the key cell contains no
observations, the default is MIDPOINTS=UNIFORM.
- MISSING1
-
specifies that missing values of the first CLASS= variable
are to be treated as a level of the CLASS= variable.
If the first CLASS= variable
is a character variable, a missing value is defined
as a blank internal (unformatted) value.
If the process variable
is numeric, a missing value is defined as any of the
SAS System missing values.
If you do not specify MISSING1, observations
for which the first CLASS= variable is
missing are excluded from the analysis.
- MISSING2
-
specifies that missing values of the second CLASS= variable
are to be treated as a level of the CLASS= variable.
If the second CLASS= variable
is a character variable, a missing value is defined
as a blank internal (unformatted) value.
If the process variable
is numeric, a missing value is defined as any of the
SAS System missing values.
If you do not specify MISSING2, observations
for which the second CLASS= variable is
missing are excluded from the analysis.
- MU=value
-
specifies the parameter
for the normal density
curves requested with the NORMAL option. Enclose the MU= option
in parentheses after the NORMAL option. The default
value is the sample mean of the observations in the cell.
- NAME='string'
-
specifies a name for the plot, up to eight characters,
that appears in the PROC GREPLAY master menu.
The default is 'CAPABILI'.
- NCOLS=n
-
- NCOL=n
- specifies the number of columns in a comparative histogram.
You can use the NCOLS= option with the NROWS=
option if you specify two CLASS= variables. See
Output 3.2.1 for an example of
a two-way comparative histogram using the NCOLS= option.
By default, NCOLS=1 (and NROWS=2) if you specify only one CLASS=
variable, and NCOLS=2 (and NROWS=2) if you specify two
CLASS= variables.
- NLEGEND<='label'>
-
specifies the form of a legend that is displayed inside each
tile and indicates the sample size
of the cell. The following two forms are available:
- If you specify the NLEGEND option, the form is N=n where n
is the cell sample size.
- If you specify the NLEGEND='label' option, the form is
label = n where n is the cell sample size.
The label can be up to 16 characters and must
be enclosed in quotes. For instance, you might
specify NLEGEND='Number of Parts' to request a label
of the form Number of Parts = n.
See Figure 3.2 for an example.
You can use the CFRAMENLEG= option to frame the sample size legend.
The variable _TILELB_ in a CLASSSPECS= data set overrides
the NLEGEND option. By default, no legend is displayed.
- NLEGENDPOS=NW | NE
-
specifies the position of the legend requested with the
NLEGEND option or the variable _TILELB_ in a CLASSSPEC=
data set. If NLEGENDPOS=NW, the legend is displayed in the
northwest corner of the tile; if NLEGENDPOS=NE, the legend
is displayed in the northeast corner of the tile. See
Figure 3.2 for an illustration.
The default is NE.
- NOBARS
-
suppresses the display of the bars in a comparative
histogram.
- NOCHART
-
suppresses the creation of a comparative histogram.
This is an alias for NOPLOT.
- NOFRAME
-
suppresses the frame around each tile.
The NOFRAME option cannot be specified with the CFRAME= option.
- NOHLABEL
-
suppresses the label for the horizontal axis.
This is useful for avoiding clutter.
- NOKEYMOVE
-
suppresses the rearrangement of cells that occurs by default
when you use the CLASSKEY= option to specify the key cell.
For details,
see the entry for the CLASSKEY= option.
- NOPLOT
-
suppresses the creation of a comparative histogram. This
option is useful when you are using the COMPHISTOGRAM
statement solely to create an output data set.
- NORMAL<(normal-options)>
-
displays a normal density curve for each
cell of the comparative histogram.
The equation of the
normal density curve is
where
mean
standard deviation 
h = width of histogram interval
If you specify values for and 
with
the MU= and SIGMA= normal-options, the same curve
is displayed for each cell.
By default, a distinct curve is displayed for each
cell based on the sample mean and standard deviation for that cell.
For example, the following statements
display a distinct curve
for each level of the variable SUPPLIER:
proc capability noprint;
comphist width / class=supplier normal(color=red l=2);
run;
The curves are drawn in red
with a line style of 2 (a dashed line).
See Figure 3.3
for another illustration. Table 3.1
lists options that can be specified in
parentheses after the NORMAL option.
- NOVLABEL
-
suppresses the label for the vertical axis.
- NOVTICK
-
suppresses the tick marks and tick mark labels for the
vertical axis. If you specify the NOVTICK option, the NOVLABEL
option is assumed.
- NROWS=n
-
- NROW=n
- specifies the number of rows in a comparative histogram.
You can use the NROWS= option with the
NCOLS= option if you specify two CLASS= variables.
See Figure 3.2 for a
one-way comparative histogram using the NROWS=
option, and see Output 3.2.1 for a
two-way comparative histogram using the NROWS= and
NCOLS= options. The default is 2.
- ORDER1=INTERNAL | FORMATTED | DATA | FREQ
-
specifies the display order for the values of the first
CLASS= variable.
The levels of the first CLASS= variable are always constructed
using the formatted values of the variable, and the
formatted values are always used to label the rows (columns)
of a comparative histogram. You can use the ORDER1= option
to determine the order of the rows (columns) corresponding
to these values, as follows:
-
If you specify ORDER1=INTERNAL, the rows
(columns) are displayed from top to bottom (left
to right) in increasing order of the internal
(unformatted) values of the first CLASS= variable.
If there are two or more distinct internal values
with the same formatted value, then the order is
determined by the internal value that occurs first
in the input data set.
For example, suppose that you specify a numeric CLASS= variable
called DAY (with values 1, 2, and 3).
Suppose also that a format (created with the FORMAT
procedure) is associated with DAY and that the
formatted values are as follows:
1 = 'Wednesday', 2 = 'Thursday', and 3 = 'Friday'.
If you specify ORDER1=INTERNAL, the rows of the
comparative histogram will appear in day-of-the-week
order (Wednesday, Thursday, Friday)
from top to bottom.
-
If you specify ORDER1=FORMATTED, the rows
(columns) are displayed from top to bottom (left
to right) in increasing order of the formatted
values of the first CLASS= variable.
In the preceding illustration, if you specify
ORDER1=FORMATTED, the rows will appear in
alphabetical order (Friday, Thursday,
Wednesday) from top to bottom.
-
If you specify ORDER1=DATA, the rows (columns)
are displayed from top to bottom (left to right) in
the order in which the values of the first CLASS= variable
first appear in the input data set.
-
If you specify ORDER1=FREQ, the rows (columns)
are displayed from top to bottom (left to right) in
order of decreasing frequency count. If two or
more classes have the same frequency count,
the order is determined by the formatted values.
By default, ORDER1=INTERNAL.
- ORDER2=INTERNAL | FORMATTED | DATA | FREQ
-
specifies the display order for the values of the second CLASS=
variable.
The levels of the second CLASS= variable are always constructed
using the formatted values of the variable, and the
formatted values are always used to label the columns of a
two-way comparative histogram. You can use the ORDER2= option
to determine the order of the columns.
The layout of a two-way comparative histogram is determined by
using the ORDER1= option to obtain the order of the rows from top
to bottom (recall that ORDER1=INTERNAL by default). Then the
ORDER2= option is applied to the observations corresponding to the
first row to obtain the order of the columns from left to right.
If any columns remain unordered (that is, the categories are
unbalanced), the ORDER2= option is applied to the
observations in the second row, and so on, until all the
columns have been ordered.
The values of the ORDER2= option are interpreted as described
for the ORDER1= option. By default, ORDER2=INTERNAL.
- OUTHISTOGRAM=SAS-data-set
-
creates a SAS data set that
saves the midpoints of the
histogram intervals, the observed percent of observations in each
interval, and (optionally)
the percent of observations in each interval
estimated from a fitted normal distribution.
- PFILL=pattern
-
specifies a pattern used to fill the bars of the
histograms (or the areas under a fitted curve if you
also specify the FILL option). See the
entries for the CFILL= and FILL options for additional details.
Refer to SAS/GRAPH Software: Reference
for a list of pattern values. By default, the bars
and curve areas are not filled.
- RTINCLUDE
-
includes the right endpoint of each histogram interval in that
interval. The left endpoint is included by default.
- SIGMA=value
-
specifies the parameter for normal density curves
requested with the NORMAL option. Enclose the SIGMA= option in
parentheses after the NORMAL option. The default value is the
sample standard deviation of the observations in the cell.
- TILELEGLABEL='label'
-
specifies a label displayed to the left of the legend that
is created when you provide _CTILE_ and _TILELG_ variables
in a CLASSSPEC= data set.
The label can be up to 16 characters and must
be enclosed in quotes.
The default label is Tiles:.
- TURNVLABEL
- TURNVLABELS
-
specifies that the characters in the
labels for the
vertical axis are to be turned and strung out
vertically.
This happens by default when a hardware font is used.
- VAXIS=value-list
-
specifies tick mark values for the vertical axis. The
values must be equally spaced and in increasing order,
and the first value must be zero. You must scale the
values in the same units as the bars (see the VSCALE=
option), and the last value must be greater than or
equal to the height of the largest bar. See
Output 3.2.1 for an example.
- VAXISLABEL='label'
-
specifies a label (up to 40 characters) for the vertical axis.
- VOFFSET=value
-
specifies the offset in percent screen units at the upper
end of the vertical axis.
- VREF=value-list
-
draws reference lines perpendicular to the vertical
axis at the values specified. For an illustration,

- VREFLABELS='label1'...'labeln'
- VREFLABEL='label1'...'labeln'
- VREFLAB='label1'...'labeln'
-
specifies labels for the lines requested with the VREF=
option. The number of labels must equal the number of
lines. Enclose the labels in quotes. Labels can be
up to 16 characters. For an illustration, see
Output 2.2.1.
- VREFLABPOS=n
-
specifies the horizontal position of VREFLABELS=
labels as follows:
VREFLABPOS=1 positions the labels at
the left of the tile, and VREFLABPOS=2 positions the
labels at the right.
The default is 1.
- VSCALE=PERCENT | COUNT | PROPORTION
-
specifies the scale of the vertical axis.
The value COUNT scales the data in units of the number of
observations per data unit.
The value PERCENT scales the data in units
of percent of observations per data unit.
The value PROPORTION
scales the data in units of proportion of observations per data unit.
The default is PERCENT.
- W=n
-
specifies the width in pixels of the curve.
Enclose the W= option in
parentheses after the NORMAL option or the KERNEL option.
The default is 1.
- WAXIS=n
-
specifies the line thickness (in pixels) for the axes and
frame. The default is 1.
