You should be able to have 32000 points in a data series in 2007 (as for
2003)

From
http://office.microsoft.com/en-us/ex...1033#Charting:

"Data series in one chart 255
Data points in a data series for 2-D charts 32,000
Data points in a data series for 3-D charts 4,000
Data points for all data series in one chart 256,000"

I have this dataseries with all the weeks for the last 6 years which comes
up to 312 week datapoints.

Unfortunately, when I want to chart a graph it only takes 255 points.
How can I get Excel 2007 to take more points in the line chart?

Thanks
