Add an Average Line in a Scattergram

In a scattergram, is there a way to have Excel show a line equal to the
average value of the data? I've been including an "extra" point in the data
that is equal to the average value and then manually drawing a line through
that point after I copy the chart into Word, but I'm hoping there's a more
elegant way to do this. I'm using Excel; 2003. Thanks!

One way: Enter XY data for two points on the worksheet (the start and end
points for the line). Use Chart | Source Data | Series (or other method) to
add the new data series to the chart. Format the new series Pattern to show
Line (automatic or custom).
