[SOLVED] QwtPlot margin

[WoldemarShiPa]

Hello. My goal is to have many QwtPlot's synchronized by x-scale, but zooming increases number of y-scale digits and graphs are not laying directly under each other. So, I get this picture:

It seems like I should set minimum width of QwtScaleWidget, but after

@graph->axisWidget(QwtPlot::Axis::yLeft)->setMinimumWidth(50);@

scale is laying under canvas:

How can I set canvas margin or solve problem any other way? Thanks

Solved:

graph->axisWidget(QwtPlot::Axis::yLeft)->scaleDraw()->setMinimumExtent();
