Hello @mrjj ,
How many subchars ? Hm, dont know. Dynamic ... five ....
Ok subcharts are not possible (resp. directly - maybe one can subclass and overwrite something).
or stacking multiple QCharts with, one axis in every chart with same configuration, is possible.....
Nevertheless, my first simpler question is not clear for me. Is it possible to mix axes with one orientation but with different range (same coordinate type). For example a Axis1 [0,10] left and a Axis 2 [0,100] right. So that a seriespoint (0, 10) connetect to left axis and a series point (0, 100) connected to right axis are both shown on the top of the chart. I hope you understand my roundabout explanation.
I cannot test it because I have no commercial version, yet.
