To navigate in the graph press "2" and "8" for up and down and press "4" and "6" for left and right. Or press the corresponding up, left right, down key of your mobile.
To scale the graph on the y-axis press "3" for zoom out and "9" for zoom in. For zooming on the x-axis press "1" and "7". It is also possible to change the scale of the axis in the options menu.
