Hello, is it possible to add a **reference range** as a solid/dotted line on a classic chart in Ignition Designer 7.9?  
I've seen tons of "easy chart" examples but was needing a range displayed on an existing chart.

Here is an example of the reference range for example, but I would like two straight horizontal lines, one at lower and one at upper bound. or this highlighted area reference range is awesome too, are either of those possible?

Update: I believe this may be the solution but going to double check tomorrow and see if this works! #gridbands[Vision Chart: Interpolation and visual bands](https://forum.inductiveautomation.com/t/vision-chart-interpolation-and-visual-bands/88491)

Yup. [That](https://forum.inductiveautomation.com/t/vision-chart-interpolation-and-visual-bands/88491/4) should work.
