Adding a layer to QwtPlotSpectrogram

[DizzyMoods]

Hello.

Is it possible to display an additional layer of data on a QwtPlotSpectrogram object? For instance, if I plot a two-dimensional function (Z=f(X,Y)) via the value method), can I simultaneously draw a one-dimensional curve (Y=f(X) or, even better, Y[n] values mapped to X[n] values just like in a simple 1D plot) on top of it?

Thanks in advance.

You can attach as many plot items ( QwtPlotSpectrogram and QwtPlotCurve are derived from QwtPlotItem
) as you want to a plot. They are stacked according to their z value.
