@tangmanger sorry, I am not actively monitoring this project. @VisualMelon will you follow up?
I suggest creating and referring to an issue that describes the new feature!

I suggest creating and referring to an issue that describes the new feature!

I think there should be a discussion if this is a feature that should be added in the library, or if it should be left as a customization example. Do other plotting libraries have similar functionality?

Okay, I will create a corresponding issue to describe this new feature in detail for further discussion.

As far as I know, this feature is not yet available in other existing WPF chart libraries. However, significance marking is widely used in statistical scenarios. During practical project usage, I’ve received frequent requests from customers for this capability, so I implemented this feature to meet real business and statistical analysis needs.

Something doesn't look right with the bar positioning relative to the ticks

I've usually seen e.g. asterisks used to show a statistically significant difference between two data-point: do you have a couple of references for this sort of symbology? (can add the info to #2163)
