About the 3D donut chart key labels

Posted by steve at 00:31 on Friday 22nd March 2024 [link]

Hello, I'm try to fix keyLabels for Pie chart(variant donut3d)

I didn't set any Fontstyle for keyLabels, but text is already bold.

Is any way to fix it?

always thank you

Unfortunately not - the bold appearance is a result of the canvas being stretched in order to create the 3D effect.

There is an HTML-based key that you could use instead of the canvas-based key. The documentation page for it is here:

https://www.rgraph.net/canvas/html-keys.html

The HTML key isn't subject to the stretching effect. If you're mixing labels (which will be stretched) and the HTML key (which won't be stretched) it will look a bit strange though. Likewise, if you have a title you could easily do that in HTML too.
