The gnuplot command to create and manage such color gradients is set palette, and hence I’ll refer to these mappings as palettes. After introducing the commands to define palettes, we’ll look in detail at a catalog of example palettes for a variety of different applications and point out their strengths and weaknesses.

2016-09-23 Replace palette by the name of your desired palette, which are listed below. Note, that this will not only define a palette, but also overwrite the first eight line styles. If you want to use your own line styles, you have to define them after the above command. In this appendix, we’ll first study how to set up such mappings between numbers and colors.
The source code is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as plot 'pdratio' using 1:2:(abs($1)>0.3?$4:1/0) with p ps 0.75 pt 4 palette Gnuplot automatically chooses the data range for the palette to map out color, which can be different from case to case. Is there way to ask gnuplot to map out color for the same data range consistently across different cases? Something like set palette maxcolor 100 2008-02-27 Suppose I have the following figure in gnuplot 4.6.2. With the minimum productive example.

For the actual data points, we use the with image modifier, while for the contours, we increase the linewidth to 1.5, instead of using the default value of 1.
