Function:xs2ap
From S2PLOT
xs2ap
Add a new panel.
Prototype
int xs2ap(float x1, float y1, float x2, float y2);
Description
Add a new panel to the S2PLOT window. The panel goes from (x1,y1) to (x2,y2) where these are fractions of the window coordinates. Individual panels can be activated and deactivated by providing the panel id to the toggle function.
