Contour labels
Hello All,
To add to that flurry of info on labels, let me add the ppl commands
that allow the contour labels to be customized. These are
CONSET - sets height, #significant digits, as well as other
properties of contour lines
CONPRE - allows text or pen changes before (prefixed) to contour label
CONPST - can be used to add text after (postfixed) to the numerical
value of a contour label
For example:
set view upper
contour/i=1:10/j=1:10/title="Defaults" i+j
set view lower
ppl conset,0.15,0 ; ppl conpre,@p2 ; ppl conpst,cm/s ; ppl contour,Customized
In the lower panel the contour labels will appear as red (@p2 => pen2) and
values like 10cm/s will be written.
Other options and uses of the CONSET command can be learned from the PPL+
manual. The syntax of the CONPRE and CONPST are simply
CONPRE prefix ; CONPST postfix
where "prefix" and "postfix" are strings that PlotPlus can deal with.
