Hi everybody,

is there a way to transpose the xAxis and the yAxis (e.g. xAxis pointing up, yAxis pointing to right) in a QwtPlotSpectrogram.

The reason why I don't simply change the data is that I want to make a fast animation of a large matrix and with
Qt Code: 
  1. setValueMatrix(QVector.mid(0,i*n_cols),n_cols)
To copy to clipboard, switch view to plain text mode 
I can very efficiently extract a sub-matrix but then the animation is row-wise instead of column-wise.

Thanks a lot
Marco
