Hi, I used wxmathplot a long time ago. It is great the someone still cares about it. But for testing it now I just added mathplot,cpp and mathplot.h to my project. I had to change some wxDOT to wxPENSTYLE_DOT. Same for brushes. But after that it compiled and ran as expected with the mp1.cpp. I used the trunk/mathplot, following cdron77's recommadation to Sergey Goncharov on 2020-03-02in the discussion list.
