Zooming on charts by selecting a range directly in the graph itself

[akamming]

Hi,

I am a user who switched from domoticz to home assistant. One of the domoticz features i really miss is easy zooming in history graphs.

2025.1 already made it better by introducing zooming. But this way it still takes a lot of time and a lot of mouseclicks to to precisely show the range i would like to see, so i propose
the following (using the best practice in domoticz which works really well).

1. Keep the current functionality above intact however don't just show 1 graph but 3 graphs when the history is shown:
   • 1 for the last for day(s).
   • 1 for the last month
   • 1 for the last year.
   • (and if you want to go the all the way: Add a fourth graph which compares the last years)
2. in the graphs add to ability to select the range with the mouse:
   • move the mouse to the 1st point of the range and push the mouse button
   • while holding down the mousebutton move the 2nd point of the range. Show visually which range is selected
   • release the mousebutton and then zoom in the what you just selected.
   • at that moment make a "reset" button appears which resets the graph to the original range:

Keep up the good work!

This is implemented.

Hold CTRL, left click and hold on the chart on the left edge of desired boundary, move mouse to right side of desired boundary, release mouse click.
