How to set changing upper/lower limit lines on graph builder

Hello, 

 

I have a simple Y vs X graph that the upper limit and lower limit are changing at different X values. Does anyone know how to do this on Graph Builder? or if there's a better way to do it?

 

Thanks,

Gary

Can you provide an example with Fit Y by X that you want to reproduce in Graph Builder?  I'm not sure what you're referring to.

I'd like to produce something like attached with the two red lines being the reference lines changing against X.

This looks like an UWMA control chart.  You can get something like this in Graph Builder if you make the limits of X another series along with the actual data.  Here's what the result looks like.Example.PNG

 

 

I made the series for the upper and lower limits and simulated data, then I stacked them to get them into a single column with labels.  See the attached data tables.
