Look at the InvokeTypes syntax (from the ActiveState link):

object = InvokeTypes(dispid, lcid , wFlags , typeDesc , resultTypeDesc , args )
Invokes a DISPID, using the passed arguments and type descriptions.
Parameters
  dispid : int - The dispid to use. Please see PyIDispatch::Invoke.
  lcid : int - The locale ID. Please see PyIDispatch::Invoke.
  wFlags : int - Flags for the call. Please see PyIDispatch::Invoke.
  typeDesc : (tuple, ...) - A sequence of tuples describing the types of 
the parameters for the function.
  resultTypeDesc : tuple - A tuple describing the type of the result.
  args : object, ... - The args to the function.

Compare to the generated call:

ret = self._oleobj_.InvokeTypes(181, LCID, 1, (9, 0), ((12, 1), (3, 49), 
(12, 17), (12, 17), (12, 17)),Source, Rowcol, SeriesLabels, CategoryLabels, 
Replace)

Notice that typeDesc is a tuple, and resultTypeDesc is a sequence of 
tuples. This seems backwards! Could that be the problem? However the method 
code for SeriesCollection has a similar parameter structure and it succeeds:

ret = self._oleobj_.InvokeTypes(68, LCID, 1, (9, 0), ((12, 17),),Index)

Could the ActiveState description be wrong?
