Corey -

Bernard Liengme has responded to your nearly identical post "Extending a
trendline to the y axis."

With the XY(Scatter) chart type, you could add any kind of line segment you
want by (a) entering several pairs of XY values on the worksheet and (b)
choosing Chart | Source Data | Series | Add ...

With a Column or Line chart type, you have less control.

I've been working with a columnar chart, and I just finished adding a
trendline (of type Moving Average) to it. However, the trendline
begins one value in on my chart when I'm really needing it to extend
all the way to the y-axis. The Backward Box under the Options tab of
the Format Trendline... is unavailable no matter what trendline type I
select, so I have no idea as to what I should do. Any help on this
would be greatly appreciated. Thanks.
