X Bar R Charts. Want something similar

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

Here’s my first pass at it. Script is in the “Process Data” Button

Second crack at it. Xbar and limits are separated into two datasets so that there are just lines for UCL/LCL. :thumb_right:

I would love an spc chart component but there’s no way I can cut a po for the whole mes module.
I second the Nice!!
