Re: [GLE-general] Filling markerd

[Francois T. <fra...@gm...>]

Hi Lukas,

There may be no better way aside from full scripting (I hope others can
prove me wrong). A first option to consider would be to define your own
markers and play with the 'set fill' and 'set color' commands. However, for
the solution to work I found it necessary to plot the data in two passes
(calling a block graph twice), otherwise the second 'set fill' command will
cancel the first. The following does seem to work:

size 10 10

sub draw_circle msize mdata
    !
    ! msize = circle radius in cm
    ! mdata = dataset parameter (required by GLE, but unused in this case)
    !
    circle msize
end sub

define marker colorcircle draw_circle

set lwidth 0.1

begin graph
    data myfile.txt
    set fill yellow
    d1 line marker colorcircle color blue msize 0.5
end graph

begin graph
    axis off
    data myfile.txt
    set fill green
    d2 line marker colorcircle color red msize 0.3
end graph

begin key
    text "one" lwidth 0.1 marker circle color blue fill yellow
    text "two" lwidth 0.1 marker circle color red fill green
end key

Ugly, isn't it? (The PDF I am joining is just as ugly because made in a
hurry, but it achieves what you want.)

At this stage of ugliness, however, it is probably better to switch to full
scripting -- ie. define a subroutine (not a custom marker) with different
parameters (name of the dataset, border color, fill color) that will loop
over your data and do what you want.

Hope this helps--

Best,
François
