Ferret How-to: coloured labels
*********************************
* Ferret How-to: colored labels *
*********************************
Hi Stefan,
The Ferret Users Guide is not as clear as it should be on the subject of
colored text labels so here is a brief explanation.
Use "@Pn" in your label string to select among the 6 predefined line/text
colors. Try
yes? GO line_samples
to see the choices.
If the color you need is not among the default choices you can redefine any of
them using the "PPL COLOR" command (see PLOT+ Enhancements Guide). The color
settings WILL be applied on the hard copy, too.
Here is a quick example to try at your keyboard.
Example:
! a sample plot
go fland 60 black basemap
! a standard black label (pen=1 default -- same as using "@P1")
label 50 -60 -1 0 .2 Here is a label in black
! a red label
label 50 -80 -1 0 .2 @P2Here is a label in red
! a white label -- redefine pen 6 to be white (100% on R,G, and B)
ppl color 6 100,100,100
label 50 -80 -1 0 .2 @P6Here is a label in white

P.S. Also try (and look at) the script
yes? GO black
for an "inverse video" approach.
