Hello,

i've got a problem with (probably) a palette settings using postscript
terminal. I'm plotting a 2D map and i want to set a palette so that
all bins with values equal to 0.0 are mapped by white color, and all
the other (non-zero) values by some different color.

I'm using Version 4.4 patchlevel 3 @ System: Linux
2.6.30.8-64.fc11.i586. The example minimal script could be as
following:

#####
reset
set view map
set palette model RGB defined (0.0 "white", 0.0 "white", 0.0 "blue",
1.0 "blue")
set term  postscript
set output 'map.eps'
splot '-' w image
0 0 0.0
0 1 0.1
0 2 0.01
1 0 0.001
1 1 0.0001
1 2 0.001
2 0 0.01
2 1 0.1
2 2 1.0
e
unset output
set term wxt
reset
####

So there should be one white bin at [0,0] and the rest of bins blue.
But the output 'map.eps' shows more than one white bin... For wxt or
pdfcairo terminal the similar script works well. Please, does anybody
have an idea?

Thanks!
Lucie
