Can a start and end date be added to the statistics graph? I see that you can choose the number of days back, but the end of the graph is the current moment. Something like in the history page.
No this is currently not possible with the core statistics graph. There’s a feature request you can vote for here: Statistic Card - Fixed Time Period by hours
Thought that is only for hours, not date.
You may be able to do this with a third party card like the Custom History Explorer Card or ApexCharts.
