[Gretl-users] Re: Saving plot/graph C/C++ api

Yes, I have looked at graphing.c and .h and I can't seem to find anything that would allow for saving a graph as a .png file. If you create a graphing using graphing.c you can not even save it manually by clicking on the graph(like you can if you use the gui directly and not use the api.). gpt_control in the gui folder seems to handle saving the plot as a png. Also, what is a gpointer? I can't seem to find that any were, is it from a different library that gretl uses? in gpt_contol. c -> void save_graph_to_file (gpointer data, const char *fname)
