Note that in order to shift the 0 of the z axis, we have explicitly got to call 'set ticslevel 0'. In the first part, we set up the plotting ranges and the function that we want to plot. Set palette model RGB functions gray/3+0.3, 0, 0 Set palette model RGB functions 0, gray/2+0.5, gray/2+0.5 Set palette model RGB functions gray/2+0.5, 0, gray/2+0.5 Set palette model RGB functions gray/2+0.5, gray/2+0.5, 0 Set palette model RGB functions 0, 0, gray/2+0.5 Set palette model RGB functions gray/2+0.5, 0.0, 0.0 Set palette model RGB functions 0, gray/2+0.5, 0.0

First, I will just give the gnu script, and then discuss segments of it.ДЇ(x,y) = abs(sin(x*x+y*y)/(x*x+y*y)) # We plot this function.

#GNUPLOT SET PALETTE HOW TO#

I suppose I need to use the вЂset palette definedвЂ™ statement too, but I havenвЂ™t figured out how to retain my automatic sampling from the palette while also having this statement in my script. However the color bar remains continuous though IвЂ™ve added a maxcolors statement below where I load the palette. My dataset is being shown as I wanted it, with colors picked evenly along the length of the palette in accordance with how many datasets there are. IвЂ™m using the lc palette method with the third column of data describing the part of the colorbar to draw from as is described elsewhere on this site. This is because IвЂ™m sampling the colors from a palette, and I want to take advantage of the palettesвЂ™ correct coloration for each stepwise change in dataset. IвЂ™ve been trying to get a discrete colorbar like the one in this tutorial but without having to specify the colors for the segments explicitly.
