Hi James,

as far as I know it's not (reliably) possible to have more than one 
SurfaceView<https://groups.google.com/forum/#!msg/android-developers/fQihJKLki7M/nz4QWV8eyxQJ>(or
 GLSurfaceView) in one Activity at the same time. Since it sounds like 
you just want to draw graphs, it would be probably better to resort to a 
custom view component and drawing on a Canvas.

If you fancy OpenGL ES rendering capabilities then you should just have a 
single GLSurfaceView and implement swiping / paging yourself by capturing 
touch events and drawing the OpenGL ES scene accordingly.
