graph editor

Hello. I need small help. Anyone knows how to get to graph editor?
I would like to know value of points in location.z for example( frame 0. location.z=100 , kind of interpolation, left/right handle position)
How I would know how many points is? Where is that data stored?

I found something like

# Save old area typeold_type = bpy.context.area.type


# Switch to graph editor
bpy.context.area.type = 'GRAPH_EDITOR'


# Do some graph stuff, e.g.
bpy.ops.graph.interpolation_type(type='CONSTANT')


# Switch back again
bpy.context.area.type = old_type

But this is general and it doesn’t give me information of single point.
Any help, link?
Thanks for any reply:)

Have a look at the fcurve.


>>> action = D.actions['Action_Jump']
>>> fcurve = action.fcurves[0]
>>> fcurve.data_path
'location'


>>> fcurve.array_index
0

# this is the fcurve for location.x




>>> len(fcurve.keyframe_points)
4


# it has 4 keyframes

>>> fcurve.evaluate(10)
0.006748685613274574

# its value at frame 10




>>> fcurve.keyframe_points[0].co
Vector((0.0, 0.0))

# point 0 is at 0,0


>>> fcurve.keyframe_points[0].handle_
                                     left
                                     left_type
                                     right
                                     right_type

# access the handles.


>>> fcurve.keyframe_points[0].handle_left_type
'ALIGNED'


>>> fcurve.keyframe_points[0].interpolation
'BEZIER'
