plsys: Set Coordinate System

Calling Sequence

...

  
plsys(n)

Description

Set the current coordinate system to number n in the current graphics window. If n equals 0, subsequent elements will be plotted in absolute NDC coordinates outside of any coordinate system. The default style sheet work.gs defines only a single coordinate system, so the only other choice is n equal 1.

You can make up your own style sheet (using a text editor) which defines multiple coordinate systems. You need to do this if you want to display four plots side by side on a single page, for example. The standard style sheets work2.gs and boxed2.gs define two overlayed coordinate systems with the first labeled to the right of the plot and the second labeled to the left of the plot. When using overlayed coordinate systems, it is your responsibility to ensure that the x-axis limits in the two systems are identical.
