Colour Markers on Line Chart

Hi Folks,

We are able to use conditions to highlight an entire row in a table using colour rules, but how do we achieve this when we want to highlight specific markers in a line chart - using the same conditional logic?

I'm building an SPC chart from scratch to include more control lines - the controls are conditional columns written in the ETL. At the moment I'm having to bring in the column (control) as a new line in parallel to the main line. This aligns with any points that fall above the average for example. However, I want the markers of the main line to be highlighted similar to how the entire row would be highlighted on a table - without having to bring in the control.

This relates to my feature suggestion here:

All responses appreciated

Kind regards,
