Heatmap histogram functionality?

[vmalloc]

I'm looking for a way to plot histogram data as a time series heat map (similar to histogram heatmap visualizations in Grafana). Is there a convenient way to plot such data in plotters?

Thanks in advance!

Just for the record, I also tried to do this. My approach was to split the canvas with split_by_breakpoints, and then use fill in each part.

While trying, I found that splitting the canvas has some precision error(?). I see the border of the splitting.

This is the plot we are thinking of

I too would really like a time series heatmap. Has someone implemented a workable solution/workaround to plot these?

If I were to take a shot at implementing them, is there some guide on how to extend the graph types? I see there is a section in the book for extending plotters, but without content.
