Dear Users and Emanuel,
Qt6 is coming around and should be available soon. QCustomPlot is compatible with Qt 5.12, but not with the next releases. I tried to use it with Qt 5.15 and I had many compilation issues with deprecated methods. From my understanding, there is a direct compatibility between Qt 5.15 and Qt6. So it should be straightforward to make QCustomPlot compatible with Qt6.
What are the plans regarding the update of QCustomPlot to make it compatible with recent Qt releases? Can we help somehow? Will it help you Emanuel if I change the source code to make QCustomPlot compatible with Qt 5.15 (and share it with you of course)? It is something you have already been working on may be?
