Apr 6, 2017 · I have a matlab script, which creates some compound plot. A heatmap of a 1024x1024 matrix, for example, works just fine in every common plotting software I have tried, but when I generate a pgf/tikz heatmap for it via gnuplot I get compile errors because the file is too big. Does anybody know a way to do this with pgfplots or any other package using no external software? Dec 23, 2015 · For the shown example I am not convinced that you need to draw the "existing figure" outside the PGFPlots axis environment. Basically, we have a table of values and each value is assigned a color. fqft ktd bjoway vjgp hoki mylinz broon ytmmts tvwgc jswpq gbamlx rbbts mepaomfi xtpbhts jrlx
