I have dug down into the help file for MSGraph 9, and I have found this

MajorUnitScale Property
Returns or sets the major unit scale value for the category axis when the CategoryType property is set to xlTimeScale. Can be one of the following XlTimeUnit constants: xlDays, xlMonths, or xlYears. Read/write Long.

I have searched the MSDN and every file on my harddrive for a reference to xlMonth. Does anyone know where I can find the new msgraph.h that contains these new constants?

TIA,

Tracy
