It would be awesome if you could add a date/time picker to the standard history/statistic-graph card. Then we wouln’t have to go the history page for further info.
And I’d like to be able to drag across a region to zoom in to that time window to look for more detail.
Hi.
Good idea that I would like to support with my vote 
The fact that there are now several (6) current WTH topics specifically dealing with suggestions and good ideas for improvements to the history graph, shows that it is effectively time to bring out something new and more performant.
I have also created a WTH topic to this theme:
And here are another 4 actual WTH topics on the same theme:
- WTH can’t I zoom in or out on history graphs - #8 by C64
- WTH lets upgrade History Graphs, they so outdated - #6 by C64
- WTH; Why can't you change the colors of lines - #4 by C64
- WTH aren't the history and statistics graph card more alike - #8 by C64
So, vote diligently and hope for a new history graph
