How to speed up response to scaling axes with code?

I am programming a chart building worksheet with vb, and I must scale
the axes based on a value within my spreadsheet. Right now, I am
using the following commands:

With ActiveChart.Axes(xlValue, xlPrimary)

.MinimumScale = Worksheets("Aux").Range("M15")
.MaximumScale = Worksheets("Aux").Range("M14")
.MajorUnitIsAuto = True
.MinorUnitIsAuto = True

End With

and doing this for each of the Primary, Secondary, and Category axes.
However, with 32,000 data points and 8 to 16 series, this takes
forever. Aside from just using a splash screen to help the user pass
the time, does anyone have any suggestions on how to speed this up or
how to do this a better way? Thanks!
 
This won't help so much with Excel 2007, but in any Excel version, it should
improve matters to construct your code like this:

Application.ScreenUpdating = False
With ActiveChart.Axes(xlValue, xlPrimary)

.MinimumScale = Worksheets("Aux").Range("M15")
.MaximumScale = Worksheets("Aux").Range("M14")
.MajorUnitIsAuto = True
.MinorUnitIsAuto = True

End With

Application.ScreenUpdating = True

Are you sure that scaling the axis is indeed the issue here, rather
than the amount of data that excel has to lay-out?
Maybe scaling the axes before setting the data for the chart would
help improve the performance, if scaling is indeed the issue.
