Hi, I would like to show you my custom card project, which allows you to clearly display your statistics in HA. The
Detailed Charts Panel is a powerful visualization solution for Home Assistant, allowing for in-depth analysis of historical data from your sensors. It offers features that go far beyond standard history, such as zoom, pan, grid layouts, various chart types, and persistent configuration. Furthermore, everything runs entirely locally using the Home Assistant WebSocket API.
The panel automatically saves your settings (selected sensors, colors, view options) in the browser (Local Storage), ensuring your analysis environment is ready immediately after a reload.
You can configurate a complete panel linked to the sidebar or you can use the dashboard card to configurate your graphs.
If you like this panel, I would be very happy about a star rating

You can also look at this video to see it in action, but don’t expect too much, I’m not a YouTuber, but it shows all the basic functions and you can turn on the subtitle translation
