Real time graph on Android API 16 no scrolling to end, no drawing of the graph #39

Hi,

like I wrote you on google+ was the graphview not updating when adding data in realtime. 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.

Attached are pictures that show the graph before (output) and after clicking (expected output).

\BR Marc output output_expected

seems that invalide() is missing...

Any workaround for that? I assume that current dev version is free from this defect right?

I tested the method proposed by "Lauszus", it works fine. Now, real time graph is updated automatically after "append". Thanks a lot.

@babaille glad to hear my commit was helpful - I was staring to think that I was the only one having the issue :) Hopefully the pull request will be merged soon then.

pull request #37 is merged, so this issue should be fixed
