I would suggest that you add a second series calculating the differences.
If need be you can plot that on a secondary axis.

Hi,

I have a line chart for month on month data

Jan'07 Feb'07 Mar'07 Apr'07 May'07 Jun'08
A 93 99 120 111 85 90

This is the Eg data. Is there a way to show difference in values.
For Eg : Jan - Feb there is a +6 difference. Then there is a +11
difference... etc
Is there a way i can show this difference on the graph automatically?
Other
than manually inserting a text box??

Thanks
Rajula
