SAS/IML Studio enables you to annotate the high-level statistical graphics with lines, curves, markers, polygons, text, and other planar objects. You can draw these graphical objects in the plot background, in the plot foreground, or in the graph foreground. You can control the color of these objects, and you can set other graphical attributes such as the width and style of pens or the typeface and style of fonts. These objects are drawn by methods of the Plot class.
The drawing methods are composed of two types: those that alter or manipulate the graphical state, and those that draw using the current graphical state. Each method name begins with the prefix "Draw". Methods that draw an object on the screen are named DrawObject. For example, DrawArc draws an arc and DrawPolygon draws a polygon. Methods that change the graphical state are named DrawVerbAttribute where Attribute refers to a portion of the graphical state and Verb describes how it is changing. For example, DrawResetState returns the entire state to its default values and DrawSetPenColor sets the color of the pen.
The available Draw methods are as follows:
DrawArc
