Hello.
I am not a developer but a user of apps created by other guys and one of the most important apps for me is Solar Assistant to monitor my photovoltaic system. It uses of course Grafana to visualize consumption, production, battery curves etc.
On my Windows 11 machine I can zoom into any of these charts by pulling a box with the mouse. But quite obviously I look at my data 90% on a mobile device, in my case iPhone and iPad and I have not managed to find out how to zoom into charts there.
Can somebody give me a hint on how can zoom in and out with these devices?
