Hello,

when I open a window in front of a GRAPH widget and close it again, some sections of the GRAPH are not redrawn, mainly parts of the graph line itself are erased. I noticed that this only happens if I have borders enabled (values > 0 in GRAPH_SetBorder). I also noticed that it doesn't happen if the diagram data is shifted. Do I have to redraw or refresh the diagram myself?

Best regards
Jan

I solved the problem by calling WM_Invalidate(hItem) periodically. I also noticed other issues when not redrawing, like a broken graph when moving the time axis slider.
