Spectrogram Graph

[Tom Krash]

Can JFreeChart be used to draw spectrograms? Spectrograms display
frequency (x axis) vs time (y axis) with amplitude values represented
as different colors.

If JFreeChart can do this, what are the basic steps?

Thanks,
Tom

Hi Tom,

No, JFreeChart can't do this at present. A new XYItemRenderer would need to be implemented. There might also be issues due to JFreeChart plotting discrete points whereas your data is continuous.

What scheme do you use to map frequencies to colors?
