Getting width and height of plot in pixels?

[Khaine]

How can I get information about width and height of actual plot? NOT including scales, only real drawing region. I want to know how many values in X and Y axis it actually stores or rather can store (which would be size in pixels of plot widget in each direction). Is size of canvas in QRect size I am looking for?

... = plot->canvas()->contentsRect().size();

... = plot->canvas()->contentsRect().size();

To copy to clipboard, switch view to plain text mode 

When being inside the render cycle and you are overloading a method having a parameter canvasRect, you can take its size as well.

Thanks for replying. I assume, that it's EXACT number of samples that will be displayed? I want to manually create function picking samples to display using multiple threads. Currently I overrided resizeEvent from QwtPlot and I want to do basic (I mean changing size of window itself) selection there.
