Graph card displaying 1h, 6h, 12h, 1d, ...

[Fusseldieb]

Is your feature request related to a problem? Please describe.
The default frontend graph (see below) is over a hardcoded time period of 24h, which makes it difficult to see changes in the last minutes, especially on mobile.

Describe the solution you'd like
A great solution would be to have buttons underneath the graph to select between 1h, 6h, 12h, 1d and maybe 7d.

+1 on implementing this feature request also in the Lovelace history-graph card. That would remove the necessity of changing around the update interval all the time.
