Excel Chart Help: Connecting two data series

Okay, so I have a scattergram (X,Y plot).

What I want to do is have two series (which I have):

X,Y point for 2009 data
X,Y point for 2010 data

I can do all of that fine. Now I want it to put a line between the 2009 point and 2010 point based on the fact that they have a shared row. So assuming I have 15 rows of data with two points on each row, I want 30 points on the graph with each “pair” connected by a short line. Is this doable?

To expand, imagine:


Person 1   2009$    2009#    2010$    2010#
Person 2   2009$    2009#    2010$    2010#

If $s are the Y-axis and #s the X-axis, I want four points, connected by two lines:

Person 1’s 2009$,2009# = Point 1
Person 1’s 2010$,2010# = Point 2

Person 2’s 2009$,2009# = Point 3
Person 3’s 2010$,2010# = Point 4

Points 1 and 2 should be connected.
Points 3 and 4 should be connected.

The problem I’m running into is that when the 2009 information is in one series and the 2010 in another, Excel connects Point 1 and 3, and Points 2 and 4.

Now, I know I can do this by creating Points 1 and 2 as one data series. Points 3 and 4 become another data series.

The difficulty lies in the fact that I have Persons 1-284 to deal with! Frankly, I’ll go slightly (more) insane if I have to create and manually format 284 series.

Help!
