Intersection of two lines
Hey. I used the scatterplot to make a chart of 4 trendlines. And now I need
to get the exact intersection of each pair. The only ways I can do it is (1) go through the data itself and find the exact intersection point - which is very slow.. or (2) bring my mouse arrow as closet to the intersection point on the graph and get an estimate. Is there a way to get the exact intersection point? Perhaps by selecting the two lines I want the intersection of .. etc? Thank you!

Intersection of two lines
Hi,
I have some information on plotting the intersecting points of lines. http://www.andypope.info/charts/intersection.htm If the lines are true chart trend lines then you will need to have a look that these sites for information on getting trend line points. Bernard V Liengme's www.stfx.ca/people/bliengme Tushar Mehta's Trendline coefficients http://www.tushar-mehta.com/excel/ti...efficients.htm Cheers Andy akr wrote: Hey.

By solving equations. This will be simple if the lines are linear - tell us
more best wishes -- Bernard V Liengme www.stfx.ca/people/bliengme remove caps from email "akr" wrote in message ... Hey. I used the scatterplot to make a chart of 4 trendlines.
