Labels on Polar Area

[luchux]

Hi everbody.
I have been exploring the idea of adding labels to Polar Area chart. I extended it in my local code, drawing arcs around the Polar Area from startAngle to startAngle + step, and writing the text along this arc.

Is there some limitation why Chartjs doesnt include labels in Polar Area? Otherwise I am keen to polish my code and ask for a pull request.

cheers

I would certainly like this functionality for a project I'm working on.

I would like the functionality too

I'm not sure if I totally follow? Mind attaching a screenshot of what you mean?

Here's an example of a chartjs polar chart with labels photoshopped on -- ideally the labels would curve along the outer of the circle... I'm also attaching an example from our old system where the charts are hard-coded, images selected based upon the data.

How are you doing this? Labels on the outer of the circle?

DO we have a solution to do it? Is this feature available in latest Chart.js version? Thanks

@meghanavc2b I had to do a workaround to get the labels -- I created an image with just the labels and then placed it as a background to the canvas element via css. Not ideal, but it works okay if you know ahead of time what you need and how it will be oriented.

here is a hack that I ended up with - radar has the labels so you can draw the"radar" behind "polar area". Just add two canvases one above the other and setup the radar so only the labels are visible (like transparent colors for the chart lines etc).
