Is there a way to draw a Horizontal line across the chart to show Upper limits and another for Lower Limits??

Second crack at it. Xbar and limits are separated into two datasets so that there are just lines for UCL/LCL. ![:thumb_right:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/2026e28c0c425034352c1b75807edf956adc75f4.gif ":thumb\_right:")
