gnuplot: label x and y-axis of matrix (heatmap) with row and column names

Question

I\'m absolutely new to gnuplot and did not find a working solution after googling.

I have a data matrix looking something like this:

  A B C D E
A 0          


        

Answer 1

ok, this question is old, but there is a much easier way implemented in gnuplot already:

plot 'result.csv' matrix rowheaders columnheaders with image

got it from http://gnuplot.sourceforge.net/demo/heatmaps.html
