There should be an option to supply a custom color function

[cal-smith]

So colors for lines/bars/pie/etc can be determined based on the data or any other metric.

A potential signature could be:

function(data: any, chart: any): string

Where data is the current data being displayed, and chart is either a reference to the chart instance, or a reference to the config (whichever is sufficiently powerful).

Good idea. Will take a look soon

This is something we need, having the color of the bar based on threshold values. Here is the design for a 1st quarter deliverable to gen1 details page.
