If I need to show only one or two entities from many available I have to deselect all others one by one. Then to return to the initial state, you need to click all of them again. It leads to a lot of clicks. And if you do that frequently it turns annoying.
I found this mechanism on Energy and History dashboards.
Not sure you know Grafana, but the approach it offers is way more comfortable.
Clicking on a single series name hides all others. Clicking on it again enables displaying all. Grafana also allows using CTRL to select desirable series.
I meant no hiding entities at all, but hiding from graphs. I mentioned it in description that this issue can be experienced on history and energy dashboards
Maybe I should rephrase the subject, But I also put effort into describing the request with detail.
