Hi. I have two charts with one common axis. The axis is time scale. I need to show time in “hh:mm:ss.zzz” format. So I created inheritor from QwtDrawScale and overloaded method label() (like in CPUplot example). I assigned objects of this inheritor to both of the charts. The second chart is located below the first, so I don’t want to show xBottom axis for the first chart. It means that I disable the axis for the plot. But in this case lines of the grids are not matched. I guess I should do something with QwtScaleDiv class, but I can’t understand what. Thank you for any help.
