Different font colors for different point labels?

[flaurida]

Hi again Chart.js,

Related to my earlier question about connecting a radar chart points with missing data, is it possible to give those point labels a different font color where the data is missing? For example, I would like to make the labels for points with no data gray. Happy holidays!

Sincerely,
Laura

This isn't currently possible. It would require modifying the scale to support an array (or function) for the point label font options and the modifying the fit and render code in https://github.com/chartjs/Chart.js/blob/master/src/scales/scale.radialLinear.js to support these arrays.

Hi,
I have a similar issue with radar plots and want to colour specific axes differently to indicate when there is no data available for an axes (in some plots we don't include point labels, hence the need for axes colouration). I assume the response for this is the same as for Laura's on point labels, we would have to alter scale.radialLinear.js to allow an array of rgba colours for the angleLines?

Thanks
Will

Is this feature still needed? I'd like to give it a shot if someone could point me in the right direction!

According to the source code, it works if you pass the array of colors to the fontColor, e.g.

fontColor: ['#f84982', '#f84982', '#86909a', '#86909a', '#86909a']

An array of colours is supported and is the best way to achieve this. We may look at allowing functions to be passed for these parameters in the future.
