Hi Clint,

In the current version of the Android app, you enter graphing mode by turning the phone sideways from the main metering screen (the one that displays numerical readings). Make sure screen rotation is enabled in your Android settings (pull down the top menu and there will be a setting). In the next version there will be an explicit button to transition to graph mode, as some users who use the Mooshimeter on-the-go have problems with accidental transitions.

Hope this helps, best
