Hi, this should be fixed with the upcoming 1.0.8-RC7, Gaëtan is working on the release.

I handle the fact that we can have missing labels or empty labels, I hope this will fix your issue.

Tested with :

  • empty dataset ( data = listOf<Sample>() )
  • empty formatted ( formatter = { "" } )

We released the 1.0.8-RC7 just now, hope this helps.

Yes, it works now…
Thank you.
