I have the following header:
Ene-08 Feb-08 Mar-08 Abr-08 May-08 Jun-08 Jul-08 Ago-08 with data. If I ad a trendline that gives me an equation, lets say: y=-3242x+13 Being x the month, if I want to get data for month Sep-08, what value should I use for x=9? Is that applicable for all the months coming, lets say next february 09 would be x=14? JP |

If your Month values are just text, then yes.
If they are real dates, Sep-08 is 39692, and Feb-09 is 39845, but from the looks of your data values I would guess that it's more likely to be text. -- David Biddulph "juanpablo" wrote in message ...
