Can force the axis' backbone extend to align with the edge of the canvas?

Uwe,
In plot matrix, the width of the plots in the far left column is smaller than the others.
And in my application, in some situation, the height also has this problem.
Seeing the pic below:

I wish, yes, maybe the canvases to have the same size in pixel.
I have thought the grid layout will layout all the plots as average size.
But now it seems not.
I don't know why.
And how to subtract the sizeHints() of such as scales?
Can you take scales as an example to tell me what should I code in the sizeHints() when I subtract it?

Thank you.
Nicho

Could Uwe give me a hand for my question in detail?

My previous answer is still valid - it is exactly what you have to do.
