Easy Chart with dynamic axis visibility bound to Power Table Selected Row

This is a chart function I’ve only ever seen in Honeywell’s Experion - chart and table are synced together and each “pen” has its own axis. Only the axis of the selected row’s pen is visible. I have been able to get almost every aspect working with an easy chart and power table, combining all three pen datasets with the axes dataset, etc

I just haven’t had any luck being able to get the easy chart to dynamically respond to the selected row. Kind of thinking this is going to have to be done via SDK, but wanted to come to y’all first!

Hmmm. Interesting. I may have a poke at this. I would expect to have to replace the native JFreeChart axis object with a wrapper that checks the selected row of the table when responding to visibility. Plus firing a chart change event when the table's selected row changes, to force a chart refresh with the new information.

I may not know enough to know better, but I figured maybe I could call the configureChart extension function since it has the JFree chart object, but I don’t think extension functions can be used like that? I think the configureChart() is working upon initialization, because the first row is selected by default, and that will actually display, but then never change afterwards.

They cannot. They are called by the component's internal implementation to give you a chance to change behavior.

But that is where any solution would go. It just needs to alter the axes to have dynamic visibility.
