PLOT, FreeFem++ scripts which investigate features of the plot() command.
The plot command can display images during the execution of a FreeFem++ script, and can store images in PostScript files. However, the details of what can be plotted, how it can be displayed, and how the plot can be manipulated, are only sketchily described. The examples in this directory are intended to ask, and answer, certain questions related to plotting.

example1: what the hell is the "cmm=string" argument in the plot() command? Apparently, it causes the given string to appear on the plot. It's not exactly a title string (which would be centered and bigger), but it does allow the user to stick some identifying words on the plot. This is good to know when a sequence of plots are displayed as part of an iteration, for instance, so that the comment string can tell you what iteration you have reached.
