Panning is unusable on touch devices #766

Pan options works great on PC with mouse or with modifier key but it is unusable on touch.

I have Ipad and iphones so that is where i tested but behaviour is that when you zoom with pinch (which is FAR inferior than drag and drag does not work on touch for some reason) you can't scroll with your finger across points to see the values because it is triggering pan gesture which is very annoying!

Also pinch is awful for touch devices because you can't pinch close to the edges. It would be ok if pan option works so you could easily get to the end of the chart but this way its unusable for smartphones

I can confirm this! My hope was that the modifer key disables panning on a touch screen, but this is not the case :(
