Thanks @boern99 for this contribution. I see there could be issues with users thinking the icons would zoom in/out the charts. Also this is a pattern that I personally never come upon, so it's not clear for me how this would work. Do you have some real world examples that use this pattern?
I see that I would have difficulties doing date/time math to see what is my current set range, because we use absolute start/end in the date textfield rather than a user-friendly approach like "Last 2 days".

@marcinbauer85: Real World example is to quickly get an overview of a longer period / a past time range: by simply clicking on "Zoom out" having all charts synchronized: chrome_TJ9qAN7GfV.webm
another tool using a similar pattern is grafana:

Thank you @boern99. Currently, we don't see a need to add this kind of functionality for the current date picker, the need and UX is not there yet. We might get back to this when we re-work the date-picker on a more in-depth level.

@marcinbauer85: As you certainly have a deeper insight into the planned features of Home Assistant and maybe there are details I do not know:
For example: an update to the charts with the function to be able to scroll to an earlier time frame, synchronized across all charts, would of course make this commit obsolete …
Just to understand your decision, maybe you can answer this question for me: Is a similar functionality planned for the charts in the near future?

[marcinbauer85]

@boern99 yes, you are correct. We have plans to add similar functionality at some point. The way you have proposed and how Grafana does it didn't convince us it's a good solution for average users.
That said, your other PR about presets sparked a conversation and in the end a user test to verify it with users. We're on track there and close to merging :)
