If you add the total series to the chart, then convert it to a line
chart type, you can right click on it and add a trendline.
Maybe you know this, but unless the category axis is numerical (or at
least evenly spaced, like Q1-Q2-Q3 etc), your trendline may be
misleading or even meaningless.

I have a stacked chart which shows data for 6 separate series identified by
month for 2010. What I am trying to do is include the data for each month
but only project a trendline using the data for months that have already
elapsed (for instance I would only want the trendline at the end of this
month to show the trend based on data for Jan, Feb, Mar and Apr).
I cant get a trendline on the graph at all let alone one that is constrained
to specific data.
I have tried including an additional data series which is the total of the
other 6 and then plot this on a secondary vertical axis in the hopes that I
could use this to create a trendline.
Can anyone help
