Spectrograms

[pfeatherstone]

Is there a way to plot spectrograms with Chart.js ?
If not, is it on the roadmap?

Hi @pfeatherstone just out of pure curiosity.
What kind of data does this get? Is it like sound waves?

Wikipedia shows a ton of options and they appear to my untrained eye quite different.

Yes it could be audio or RF data.
