gnuplot development

I have applied the patch to both 4.2 and cvs.

ok, I overlooked the go.m script.

Now I understand the suggestion that Octave use rgb2gray when the output
is mono.

It stays color -- see the line
colormap(rainbow(4));
in the script testing go.m and similarly in go.gp. Have you tried these
examples as well?

that last comment was me ... don't know why I came up "nobody" ;-)

Petr,

Nice job. All my checks work as well.

In the event that the custom colormap is not BW what happens?

Please test the updated patch 02. I hope it works now for all plots ... I
couldn't find any plot in gnuplot neither Octave where it fails.

Petr,

I've applied your patch. For the examples I ran previously, I don't see a
change.

For your simple example co.ps and mono.ps are the inverse of eachother.

Patch: Let postscript choose always colour palette for interpolated
colours
('set palette defined', 'set palette file') and colour/gray according to
Color
otherwise ('set palette gray', 'set palette rgb').

Ben, please test it with Octave. It seems there is a bug somewhere; please
try:
a=1./hilb(42);
colormap(rainbow);
colormap(flipud(gray));
imagesc(a); colorbar
print('mono.ps', '-dps');
print('co.ps', '-dpsc');
