Dear Miccs,

Can you explain how and where to apply this patch? Thanks a lot!

Kind regards, Jan

here you can download patched - ready to use file:

if you are scared of the contents of downloaded files just check its content by comparing the contents of this file with the original unmodified using for example total commander (on windows) or double commander / krusader on linux.

you can apply that patch yourself - but i cannot give you exact command(probably you are on windows) - git client can do it (from what i know) or other port of patch tool from linux.

on linux its simple -
patch -p2 < ../qcustomplot.patch

thats it.
google for a windows solution - its a "diff patch"

Dear Miccs

Thank you for this patch, it works perfect now
