Trend line not showing when selected

I selected the trend line option for a chart with 'Stack 100%' as the option but it doesn't appear to be displaying the lines.

Hi @ed.s - upvote by clicking :+1: on the first post

Brilliant, thank you Flamber :+1:

Not sure if this is related but also seeing an issue where the trend line switch doesn't appear at all.

This is using much of the same data and types as the previous chart. I noticed similar bug was identified in v35 but that appears to have been solved. Let me know what else you want to see to help debug.

@ed.s Linking to things is a lot more helpful.

@flamber As requested. Similar issue linked to this topic
