plotmatrix canvas size after rescale

[bbrondel]

Hi all.

I'm playing with Qwt and having some trouble with the plotmatrix example. In the example, I added a line in the MainWindow constructor after the calls to setAxisScale, as follows:

setAxisScale(QwtPlot::yLeft, 2, -2, 2);

setAxisScale(QwtPlot::yLeft, 2, -2, 2);

To copy to clipboard, switch view to plain text mode 

which calls setScaleAxis on the leftmost plot in the bottom row with limits -2 and 2. When I run the program, the scale comes out right, but the bottom row of plots is taller than the other rows. A screenshot is attached. What I want is for all the plots in the matrix to have the same size. How can I acheive that?

Thanks.
