I have a Perspective XY chart displaying data in column format. I'd ideally like to add vertical markers for high and low limits like shown.

I have tried making a second data source for the limits to add as a separate series but the chart seems to not support displaying more than one series? There also doesn't seem to be a good way to add labels above the columns either?

You can pass the color and Legend as a parameter

Then use deriveFieldsFromData property for color

Add dummy series to render Line. Make stroke opacity 0 and use bullets prop for label
