Drawing commands

The Drawing commands act on the display. The scale of the

display depends on the current aplet’s Xmin, Xmax, Ymin,

and Ymax values. The following examples assume the HP

39G/40G default settings with the Function aplet as the

current aplet.

ARC Draws a circular arc, of given radians, whose centre is at (x,y)

The arc is drawn from start_angle_measurement, and

end_angle_measurement.

end_angle_measurment:

Example
