Thanks Paul,

The issue with the graphing activity is that I want to leave as much of the screen as possible available for the graph. I think I’ve worked around the issue though, and the new interface should be more intuitive. I separate the touch areas of the left and right axes, so you can pan and pinch-zoom the left and right axes seperately just by manipulating the two sides of the chart. Buffer mode and XY mode are hidden in a pop-up menu controlled by an onscreen button.

Will push to beta later this afternoon

Thanks
