Problem regarding QWTPLOT

[sudheer168]

Hi I am using QT4.4.0 and qwt-5.0.2.In this I am using QwtPlotCurve class for plotting. For plotting I used setData() function its working properly ,but if I use setRawData() then the execution get breaks with in a couple of minutes .I was not able get why it happening .
So please help me to solve this problem.

With regards,
Sudheer.

setData() copies the arrys, setRawData() stores the pointer to your array only. Of course then you can't delete the arrays without clearing the curve object before.

If possible I recommend to use a Qt container instead of the double arrays. Then you don't need to take care about pointless copies or bad references.
