There is no solid plans for docs, but it would be nice. We can probably start that after the new Chart release. I aimed to have a lot of info in the controls themselves if you haven’t seen this and it helps.
Having editable breakpoints in charts is definitely on the list, it’s not a feature of Chart.js itself. I’d start by trying to add breakpoints to the charts container if that helps. Adding in padding and negative margin of the container on a certain breakpoints to try get around the aspect ratio might help. And then just having a separate charts for different breakpoint if all else fails. Not ideal, but hopefully these ideas help.
Have a great weekend.
