Hi Anne -

Essentially you need a two-point series for each additional line you
need to draw. A bit of work, but here's a manual approach.

Suppose your data's in A1:D10, and Series 1 has X in A1:A10 and Y in
B1:B10, while Series 2 has X in C1:C10 and Y in D1:D10. Choose Source
Data from the Chart menu, and click on the Series tab. Click on the Add
button, put the cursor into the X Values box, then select cell A1, and
hold CTRL while selecting C1. The X Values box will display

=Sheet1!$A$1,Sheet1!$C$1

Clear the ={1} from the Y Values box, keep the cursor in the box, select
cell B1, and hold CTRL while selecting D1. The Y Values box shows

=Sheet1!$B$1,Sheet1!$D$1

Click Add again, and this time pick your pairs of points from row 2.
Repeat until you've run out of rows of your data.

With a little programming, you can make this less tedious.

I have an xy-scatter plot with 2 series, say Series1 and Series2. The data
is arranged in 4 columns, Series1-x-values, Series1-y-values,
Series2-x-values and Series2-y-values. I would like to draw a line between
the Series 1 and Series 2 xy-coordinate for each row in my data. Does anyone
have good tips on doing this? I would appreciate any help.
Thanks,
Anne
