[URGENT] How to bold sub label/title?

What I wanna achieve is to make the 2nd label (sub-label/sub-title) bold.

...
labels: [
     ["Main Label", "This is a sub-label" /* i wanna make this sub label to be bold */ ], ...
],
...

The closest solution I could find online, but it’s inactive: https://stackoverflow.com/questions/46221425/chart-js-make-part-of-labels-bold

also tried https://jsfiddle.net/Leelenaleee/3d50fkL9/26/

But none of them is working, so I’m here asking for help, thanks in advance

Seems to be working fine, improved a bit by adding padding at bottom so text doesnt get cut off, also instead of drawing white box make default text transparent. Depending on your subTitle text length you might need to also add some padding on the right.

To make it bold did you replace the italic to bold in the fontStringSubTitle option?

Solution:

instead of setting white, i set to transparent.

ticks: {
    color: 'transparent',
},
