Pardon me for jumping in.
Scott,
You can find object model for MSGraph5 and up. Search for a file named vba_grp*.*. For MSGraph5 as far as I remember name was different and was located in MSGraph dir. Later versions seem to be located under Office dir (and as I remember during install VBA help is optional).
For your problem syntax would be :

myform.myGraph.object.application.datasheet

However I think this is related with your web chart problem. IMHO Excel is way better and faster than MSGraph. MSGraph9 and up has PEM almost identical to Excel's. So if your version is 9+ you could simply use Excel developer help too.
As another side note if you would use MSGraph instead of datasheet use code like :

#DEFINE TAB_ CHR(9)
#DEFINE CRLF CHR(13)+CHR(10)
* Data prepare *
wait window nowait "Filling cell values..."
MCGDATA = ""
nCols = fcount()
for ix = 1 to nCols
  MCGDATA = MCGDATA + iif(empty(MCGDATA),"",TAB_)+field(ix)
endfor
MCGDATA = MCGDATA + CRLF
scan
  for ix = 1 to nCols
    MCGDATA = MCGDATA + iif(ix=1,"",TAB)+nvl(transform(evaluate(field(ix))),"")
  endfor
  MCGDATA = MCGDATA + CRLF
endscan
* Data prepare *

create cursor testgen (genfld1 g)
append blank
append general genfld1 class "msgraph" data MCGDATA

Filling cell values using datasheet is much slower.
