Spectrogram / waterfall type visualization

[flothesof]

Hi there,
I'm investigating how to build a simple spectrogram / waterfall type visualization.
It seems that RTGraph could be adapted to provided this functionality.
However, the visualization that needs to be obtained at the end is more a 2D image than 1D signals as shown in the talk and proceedings.

Do you think it would be possible to implement such a visualization using RTGraph? If so, could you point me to some relevant links regarding this?

Thank you for sharing this project.
Best regards,
Florian
