Hello, 

 

You can always update the upper and lower limit of your Graph by just making click on the number at the top and giving it any value. The same with the lower value. Also remember that there is an option of autoscale by default so it would be better in your case if you disable it. I will show you some images of how to do is if you are still wondering how to do it.

I use cursors for this. You need to create the cursors manually or programmatically. Then you can give the cursor a name and value.  You can set the high and low limits and draw the cursor without data on the graph.

Just edit the top and bottom and run.

You could add two additional plots one for hi the other for low.

 

The advantage you get using that approach is you can see if the limits change AND eb able to use the "fill to" option to highlight the are between the measured and the limit if you so choose.
