Heat Map from Survey Data AND legend

[JenMcRuer]

Hello, 

I have a heat map from survey data, and have turned on visible legend. However, the title of the legend is the survey name, and I would like to change this. Additionally, the legend heat bar has shows no reference to what it refers to (i.e., high, low density). 

From help articles it says to open in map viewer classic to make changes. But when I open in map viewer classic, it says it can not show the heat map version, and reverts to the original map (individual plotted points) which isn't what I want to edit.

Any advice appreciated! 

Thanks

Found out how to change legend title (renaming layer)... but still stumped on legend reference text....

Are you making a Web Map?

Yes I am.

Okay. You will most likely get more help in a different form. It depends on the product you are using as to where you should post. I'd be happy to move this for you, but could you please provide some more info on your platform?

Are you using Web App Builder or Experience Builder, and is this an AGO or Enterprise environment?
