The G3D Procedure

Example 4: Generating a Simple Scatter Plot

Procedure features:
SCATTER statement
Sample library member: GR29N04

[IMAGE]

This example shows a scatter plot that examines the results of measuring the petal length, petal width, and sepal length for the flowers of three species of iris. The SCATTER statement in this example relies entirely on procedure defaults, which scale the axes to include all data values, label the axes with the names of the axes variables, divide the axes into three even intervals, rotate the horizontal plane 70° around the z axis and tilt it 70° toward you, and display the plot with the colors that are defined for the colors list. The data points are represented by pyramids, which are connected to the horizontal plane with needles.
