Hi guys,

I am new to QT and QWT. I currently have 2 spectrogram plots in a vertical layout. The top one has a scrolling time y axis (adapted from the cpuplot example). The bottom one has a predefined y axis. I am trying to align the 2 plots' x-axis.
Basically, I think i would need to get the label size of top scaledraw and somehow apply it to the bottom plot but not sure how to do this. Any help (or if theres a better way to align two graph axes) would be much appreciated.
