Hi list,

While playing with PyQwt5 I stumbled accross QwtPlotSpectrogram which appears 
to be the official replacement for the "engineered ImagePlotDemo.py" which I 
think not only I am using to display data matrices.
But I cannot make it work for me:

>>> b = qwt.QwtPlotSpectrogram ()
>>> C = qwt.QwtRasterData (c)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: Qwt.QwtRasterData represents a C++ abstract class and cannot be 

Docs say QwtPlotSpectrogram.setData wants a QwtRasterData object and this 
class doesn't seem to have children. What am I missing?
