Crystal Reports Homogenous Values in Line chart

Message

   Hello,

I've created a Line chart in crystal report XI R2. 

I set Onchange of to "DateTime" and Showvalues for to "Ivalue".

X axis values are based on the exact data values from Stored Procedure. So how can I set predefined values in the x-Axis instead of crystal reports picking values from the Stored procedure dataset. 

Ivalue
DateTime

23
6/15/10 13:40

26
6/15/10 14:40

5
6/15/10 15:00

8
6/15/10 16:00

So that my report looks homogenous for different set of Date range.

Could you pls help me in getting this.

Thanks,
Harry Vidhya
