Issue with QwtPlotRescaler

[Sébastien P. <per...@ge...>]

Hi all,

I have an issue with the object QwtPlotRescaler.

I have a QwtPlot to which I attach a QwtPlotRescaler.
I let the default layout flag alignCanvasToAxis to false.
I attach my own plot item for which I implement the method draw().

The point is that in the draw() method of my plot item  the x and y scales
given by the QwtScaleMap arguments are not equal as they should be (if I
interpret well the way the rescaler should works).

If I set the flag alignCanvasToAxis to true, then I get the same scale for
x and y.

I think the problem is that the method QwtPlotRescaler::rescale(const QSize
&oldSize, const QSize &newSize) uses the size of the canvas to update the
axes according to the reference axis, ignoring the actual size of the axes.

Are there someone who find the same issue ?

Cheers, Seb
