Hi all, How would I go about having only one Y-axis displayed for all the series data, regardless of which series is selected? The data comes via a tag query history binding via transform on the selected paths. And as I am typing I just realized I could probably bind the `trends.series` to the first selected path/series name... **EDIT:** One caveat is that all the series use the same axis, and each "column" name is the same, though the name of the series is different. Here is a pic of the two series and one data point. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/d/ad11cad789ac61c92f95d6bdff4dc7d146eb5a44.png) I created several trends, each with a different series OK, got it! Each series needs one trend, which needs one column. Is there another way to do this? Thanks, Mike ---
