QwtPlot Canvas Size Hint?

[umituzun84]

Hi All,

I have 3 QwtPlot in vertical layouted widget as you can from attached screenshot. When I zoomen in or out in my any canvas as you expect that scales changes so layout sizes changing too. Then my end-to-end alignment in each QwtPlot is breaking down.

At this point, how can set my canvas size fixed. So my all 3 canvas left and right point lined up on same line.

Thanks in advance.
Regards.
