Spectrogram data resolution...

[uppu]

My Data resolution is not matching the QImage size that is created in the function QwtSpectrogram::renderImage().

I need the Image that could accurately match with my data resolution, and
QRasterData(double x, double y) should always have (x,y) exactly matching my data resolution.

How to handle this situation?

Now the Spectrogram image is created incrementally and appended to the previous image.
But the image itself shows data for future it souldn't happen.

The problem is that image width that i need is too much more than the screen width itself, In otherwords, for my data, screen is too small while the image is too big .

How to handle this situation?
