I have several sources in my energy dashboard. Some of them are small, some are large. Some are only twice a week (charging the car), some are daily. The problem is the scale of the vertical axis. If there is one large bar on Monday, I cannot compare the bars of rest of the week, because this large bar dominates.
Feature request: as a user I would like to be able to hide/show sources, when I click on the coloured box of the source overview below the graph. Clicking on a source will hide the bars for this source, clicking again will show the bar again. This allows me to compare the usage of sources that are relevant for me.
I would suggest that this is not stored, and next time a user opens the Energy screen, all sources are shown (again).
