Hi Yi, Thanks for the sample. I actually went back to my previous tests and I now remember the issue I faced with `registerPostUpdate`. Once I have the width of the axis, I need to update the chart with a new option. Unfortunately, it doesn't like that even when passing `lazyUpdate: true` and I get the `Uncaugt `Error: `setOption` should not be called during`. I tried using `ecModel.mergeOption`, but since it's postUpdate, it won't reflect the change until the next render.
Any suggestions?
