I have a trouble with my qcustomplot widget. So i have some dataset, plot it, then use rescaleAxes() method, and everything is fine, except scale ratio is not 1x1 ( circle looks like ellipse on my plot ). So I use setScaleRatio method to fix this problem, and what I get is right proportions, but broken axis range ( plot doesn't longer fit in the screen ). I need both ( right proportions ( 1x1 for x-y) and graph completely fitting widget area. Can someone please help me?
