Dear list'ers
I'm struggling with a surface shade plot and can't figure out what I'm
doing wrong. I can't find any info other than the plplot homepage
examples regarding PerlDL, and all I get by following those examples are
just black surfaces...
Anyway, here's my problem (and it should be simple to solve, argh!!!):
I've got three different arrays, $lon, $lat and $value.
$value[0] corresponds to $lon[0] and $lat[0] and so on.
$value takes values from 0.0 to about 20.0.
The lon/lat grid resolution is 2.5 X 2.5 deg and may take any
geographical value (-180 to180 and -90 to 90)
I'd like to make a surface shade plot (blue -> green -> red) showing red
for the highest values.
Sorry to bother you with such basic questions...
Cheers,
Ked
