  • Thank you, Sven. It's no big deal. I replaced the GRAPH auto scrollbar with a SCROLLBAR widget. Regarding the next release: Will it be offered to STM32 customers, too? Best regards Jan

  • Hi, the automatically attached vertical scrollbar works in the opposite direction of the diagram. The bottom scroll position is on the upper end and vice versa. Is there a way to mirror the vertical scrollbar? Regrads 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.

  • Hi, it's me again. I have some difficulties understanding the Y/t GRAPH widget in all its complexity. What I want to do is logging data over a time interval which is longer than the visible interval on the screen. It would be nice to have a moving diagram with new values shifted in on the left side.

Do I have to redraw or refresh the diagram myself? Best regards Jan

The default frame setting is 5 pixels, so I have to set the frame to zero in each ICONVIEW item I am using? Regards Jan
