Where is the 'help' for Crystal Reports Object Library...?

I want to manipulate my report through visual Basic code, specifically I want to change the way my graph groups on dates. So the user can select group by DAY, WEEK, or MONTH.

So I've got so far as

Dim graph As CRAXDRT.GraphObject
Set graph = cReport.Sections(1).ReportObjects("Graph1")

But I'm trying to navigate through the object library with no help, Crystal Reports help is all about the application, not the VBcode.

SO

Does anyone know where I can get documentation on the CRAXDRT object library
OR
Does anyone know how to change the way a graph groups on a field...

The help files for CR never worked for me in the IDE of VB. I did have to search the HD for the .chm/.hlp files though. ;)
Usually its somewhere in the "?:\Program Files\Seagate Software\Crystal Reports\Help\en"
Or
?:\Program Files\Seagate Software\Crystal Reports\Developer Files\Help
depending on your version.

ah!

help galore.

IN C:\Program Files\Crystal Decisions\Crystal Reports 9\Developer Files\Help\En

I thought it would either be in the VB IDE or the Crystal Reports Application, but no, they chose to hide it away. sneaky devils.
