PyQwt Curve dataset immutable? No setRawData?

[thaivim]

Just wondering if there's any possible way to prevent copying the curve dataset as happens in the QwtPlotCurve::setData call. I see PyQwt doesn't export setRawData and as far as I know, the underlying QwtPlotCurve arrays are immutable at least from my particular vantage point.

In building a real-time plot with a lot of curves in PyQwt, I'm starting to notice a lot of contention each time I need to add points to my curves. I'm using python's list(), but I don't think numpy arrays would help (as the copy should still happen).

Any ideas are welcome and much appreciated.

setRawData is only a leftover from very early Qt versions ( Qt 2 or 3 - I can't remember ) where Qt containers were not implicitly shared. Don't care about it much as you have more or less the same when using Qt containers.

Hi Uwe, thanks for your response. So I take it, I should try to see if i can manage or at least access a mutable container QwtCurve uses?
