I select data points with same names such as kwh but all with different device names in a chart for comparison. In the legend all show only names without device names. I remember that before version 2.5 legend includes device names. I need to show users to compare data points in watch list chart. They must have the same question in mind.
Watchlist chart only shows names in legend without deviceNames
You're correct. I took a quick peek at the history of the code producing that chart, and didn't find an obvious culprit. So, I've created a git issue for this: https://github.com/infiniteautomation/ma-core-public/issues/828
Thanks for letting us know.
