# using bpy.ops.*.view_all

I have this at the end of a function, so every time I execute it, I would like to use view_all for those three area types from whatever area is active. But I get an obvious context error.

        bpy.ops.action.view_all()
bpy.ops.graph.view_all()
bpy.ops.timeline.view_all()


So, how can I use all three from a single context area?
