gradient vs stepped data

For some data it might make more visual sense to see it in stepped form, not a pure gradient, i.e. instead of going from rgb# 0, 1, 2, 3, 4, 5, 6, 7, to go 0, 2, 4, 6, 8, or 1, 4, 8, 12, 16. to make the representation more visually helpful to humans to be able to differentiate different values.

Also it might sometimes be better to see the data as a gradient, so best to create another chart, rather than modify the existing one.

Locate the Python code that renders the HTML heatmap and identify the current chart entry point. Read how the existing gradient representation is produced, then determine how a separate stepped chart would fit alongside it. Done means users can choose or view both gradient and stepped representations for the same data.
