Waterfall plot with QCPColorMapReturn to overview

I'm trying to create a real-time waterfall plot of signal power spectrum based on QCPColorMap, and every time on redraw i have to change each cell by calling setCell of QCPColorMapData, for all data points. On big waterfalls I have giant overhead and lags. If you create method scroll() in next version, like in QPixmap, anybody who want to plot same waterfalls will be able to scroll waterafall on single row and then change only one row on each redraw...

it seems like you could probably implement this yourself pretty simply by modifying the source code.
