G3D Procedure

Example 7: Generating a Rotated Scatter Plot with Modified Axes

Features:

Scatter statement

SCATTER statement options:: CAXIS=; COLOR=; ROTATE=; SHAPE=; SIZE=; XTICKNUM=; YTICKNUM=; ZTICKNUM=; ZMAX=; ZMIN=

This scatter plot modifies the procedure defaults. It specifies a shape for the data points and classifies the data by color. For the axes, it specifies blue as the axis color. It specifies five major tick marks for the Y axis and two major tick marks for the X axis. For the Z-axis, it specifies five major tick marks, zero as the minimum axis value, and one hundred as the maximum axis value. It also rotates the X-Y plane –15 degrees around the perpendicular Z axis.
