[Gnuplot-info] pm3d problem

[Henry S. A. <Pat...@Co...>]

Hello,

I am using gnuplot 4.2.2.

I am trying to generate some pm3d plots in postscript format.
When I execute these commands:

set pm3d map
set samples 100
set isosamples 100
set palette gray
set palette gamma 0.5
splot sin(sqrt(x**2 + y**2))/sqrt(x**2 + y**2)

-- the plot looks great (in the x11 terminal). Now if I do:

set term postscript enhanced
set out "test.ps"
replot

-- and I look at the file test.ps, the plot looks worse than the x11
version -- there are white grid lines throughout the image making it look
pretty bad. Does anyone know how to get rid of these ugly grid lines?
