Chart - Plot Constant Line Based on Passed Parameter

I’d like to be able to use a Dynamic Property (passed from another screen) as a constant value to be plotted on an Easy Chart. I don’t see that there is any way to do that. Am I missing something, or is there another way that makes more sense? Thanks for any help you can offer.

I figured out a solution. I bound the Calculated Pens to a dataset and was able to integrate the passed parameter that way.

For anyone else interested, to do this you’d make a constant calculated pen, and then use the cell-update binding on the Easy Chart’s expert-level tagPens dataset property to bind the passed parameter into the pen dataset.
