#2690 — postscript splot x/y/zlabel rotation and colours

Hi all,

It's been two/three years since I last picked up GNUPLOT so I'm very rusty! 

I am trying to splot some 3D data. The default terminal on the Unix cluster changes colour according to the Z-value but when I change to a postscript terminal the Z-value is no longer being represented by a change in colour, rather the colour changes according to how close the splot z-value is to the 0,0 of the x and y dimension. 

Also I am not sure how I can rotate the labels along the axis, as the splot of 3D data puts the x and y axis on 45 degree angles. My shameful basic code is below. I would really appreciate any help.

Many thanks
Anthony


set term postscript eps enhanced color linewidth 2 solid font 'Helvetica,20'
set output "color.eps"

set pm3d

set xlabel "ASN - HIS (nm)"
set ylabel "ASN - PRO (nm)"
set zlabel "FES (kJ/mol)"

set ticslevel 0.2
unset colorbox
unset key

set contour base
set pm3d at bs
splot 'FES_mouth.dat' with pm3d

I am further with one of the problems. 

Turns out that for some reasons, all my data points (which are between 0 and -300) are all coloured yellow (zero value) as displayed when I set the colorbox on. For some reason the z value is not actually mapping to the correct colour according to the colorbox.

Any thoughts?
Thanks

Please tell us what version of gnuplot you are using and provide
an example of the data.   Since you have not given a "using"
specifier, the data handling depends strongly on what is found
in the first line[s] of the data file.

You might also take a look at the online demos to see if one of
them illustrates the type of plot you are trying to produce.

Try adding

unset surf

Although this usually makes it red not yellow?

Or you could try set caxis[*:*] if the yellow is because your range of colors is off.
