The android version used was 4.1.1 on a Samsung Galaxy S3 LTE.
I tested it now with the emulator on the versions 2.3.3 (API 10), 4.0.3 (API 15) and 4.2 (API 17): On this APIs is the graph updated like expected.
Only when running a emulater with API 16 (4.1.2) or the phone (4.1.1) is the graph not drawn.
The strange thing is, that it is updating the labels on the y axis (but not on the x), and thereby not drawing the graph. It updates the graph as soon as one clicks on it.
