The Semi-circular Progress property scaleUnitsPost is not used


Posted by Joachim at 14:54 on Tuesday 30th May 2023 [link]
hi,
I found that property "scaleUnitsPost" has no effect when defined for "SemiCircularProgress" type charts. I had to specify "labelsCenterUnitsPost", "labelsMaxUnitsPost" and "labelsMinUnitsPost" instead. Can you check this?

The scaleUnitsPost property is for the scale, which is not shown by default. Here's an example of it being used on a chart that's showing the scale:

hi,

OK! But then you should update your doc, as you state eg. for "labelsMaxUnitsPost": "If left as null this falls back to the scaleUnitsPost property".

Cheers - I'll look into that!
