FFT plot using plotly


I am pretty new to Grafana and has been using it for 3 weeks.

I use Elasticsearch as a database and would like to know if there is any way to plot fft (fast fourier transform) graph on Grafana?

From what I found, I have seen some people display it with heatmap (hiveeyes) or plotly plugin (running a power plant at 12:13). But I do not know how they do it or what is the data structure they use.

Thanks in advance

I need something similar, are you able to visualise a fft graph?
