[RESOLVED]Making a chart using accumulated values (by myself)

Hi, there!

I'm in trouble about that... :rolleyes:

I need to make an chart (line chart) using data from an Access' Table and Crystal 8, but it must show "progressive values"...

Example:

Month 01 - $1,000.00
Month 02 - $900.00
Month 03 - $2,000.00
and so on...

The standard way only shows me the month´s current value, and I need that they are accumulated month by month...

Example:

Month 01 - $1,000.00
Month 02 - $1,900.00 (Month 01 + Month 02)
Month 03 - $3,900.00 (Month 01 + Month 02 + Month 03)
and so on...

Is there a way to do that ? :confused:

Thanks in advance.
