I'm using gauges with subtitles and the highvis theme. I'm doing some changes to the json and css of the theme but there's one thing I can't find there.
I'm seeing rectangle with a gradient from transparent to white displayed on the right of the subtitle (see screenshot). I guess it would work well if it went from transparent to black (my background color) and the subtitles were too long for the available space. They would nicely fade into the background. Is this something that can be configured in the css/json files of the theme?
