I recently discovered the part of pgfplots that allows you to add external graphics with the
\addplot graphics command.
I have a matlab plot converted to tikz with matlab2tikz. Problem is that the plot contains A LOT of data points and I don't want to process them every time I compile my document.
My question is as follows:
Is it possible to externalize the curve of the plot only, such that I'm able to alter the axes/legend/title at any time without processing all the curve data again (i.e. I compile the complete tikz picture once, then externalize the curve only as a PDF file, such that that PDF can be used later with the
\addplot graphics.)? Maybe this is possible with the
\addplot graphics command but I can't find out how.
