[[FEATURE] PowerChart missing EngUnit display - Ignition - Inductive Automation Forum](https://forum.inductiveautomation.com/t/feature-powerchart-missing-engunit-display/92511/6)

In the graph, it’s not possible (yet).

The next best thing I could find, was adding it to the Pen Name. When creating a Pen for the Power chart through scripting, you follow the [Pen's properties](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/perspective-components/perspective-chart-palette/perspective-power-chart). You can get the EngUnit through [your]tag/Path + .EngUnit. If you read that value and put it behind your pen name like [this], you get something like this.

I hope this helped, good luck!
