Stacked Curves - QwtPlotMultiBarChart

[GG2013]

Hallo,
I wanted to plot multiple curves in stacked form. Using QwtPlotMultiBarChart (& following qwt example code) I have achieved as shown in Screenshot.png. But I would like to have continuous curves as in StackedCurvedSurface.png. I was thinking of using sample width of bars to a very small value can do the job but couldn't figure out the code. Or, is there any other way to do that?

Any help would be greatly appreciated.

Use 3 QwtPlotCurves with a brush to fill the area below the curve. Do the stacking by summing up the y coordinates. Use QwtPlotItem::setZ() to control the drawing order of the curves ( blue -> green -> red ).

That's fantastic Uwe! It didn't come in my mind! It's working fine now.
