@jsulm Oh,thank you. And so sorry I didn't make the details clear. I need a multiple coordinate system ,so QChart, qwt or QCustomPlot may not be suitable.
Now I use GraphicsView to draw the costomized coordinate system on the background and the waves on foreground.When zoomed, panned and getting new data, it would receive update() signal to repaint,both background and foreground.
So,do you have other advices ,thank you.
