VB.net chart help

[wstow]

I'm creating a chart using a add-on I've created with Vb.net in visual studio.

I'm about 95% done but can't figure out how to do this: (code recorded from a macro)

ActiveSheet.Shapes("Chart 1").ThreeD.RotationY = 30

in my VB.net code.

I've tried.

Globals.ThisAddIn.Application.ActiveSheet.Shapes("Chart 1").ThreeD.RotationY = 30

--This gives me an error (can't convert "Chart 1" to an integer)

and
Globals.ThisAddIn.Application.ActiveSheet.Shapes(0).ThreeD.RotationY = 30

--this doesn't give me an error but doesn't do anything.
