I would like to remove the outline on my meter chart (see image).
I can't find any setting in the GUI to do this. The only way that I have found so far is to make the chart background black so that it doesn't show, but this isn't really acceptable as I don't want a black background.
This is what I'd like it to look like
Is this just missing in the GUI? Is there an API I can use in a script to achieve this?
