Is there a, preferably simple,  way to generate the % change +/- of a Crystal Reports XI generated regression line percentage from start to end?

Are you looking for a chart or just a table of the data?

What is the formula for the regression percentage?

Crystal does have a line chart with percentage

I apologize,   I have the chart and a regression line on that chart. What I am trying to gain is the sinlge value actual percentage deviation of a Crystal generated regression line from starting point to end point (+/- x%)

Maybe this is a better way to phrase my question.

Based on the attached sample chart how do I automatically within Crystal generate a single percentage value at the end of the report that reflects the percentage (% +/-) change in the trend line as generate by Crystal Reports XI for that chart group.

Or optionally, thought not preferable, how do I get the values created by Crystal Reports XI to generate the trend line.

I don't know how to get those values.  

I doubt there is a way to do the % without getting the values for the trend line.
