Take snapshot and share
GraphView provides build-in functionality to generate a screenshot to save as file or to share it directly via Android share screen.
It's also possible to just generate the snapshot and use the image data for your own purpose.
This are the simple calls:
// directly share it graph.takeSnapshotAndShare(mActivity, "exampleGraph", "GraphViewSnapshot"); // get the bitmap Bitmap bitmap = graph.takeSnapshot();
The runtime permission
WRITE_EXTERNAL_STORAGE is needed!
