Plotting series names as numerical values in a scatter graph?

Hi all,

So I have three columns of data;

a list of names in column one that I want to be the name of my data series

numerical value 1

numerical value 2

I want to plot numerical value 2 agianst numerical value 3, instead it plots 2 and 3 as separate series.

I appreciate the explanation above isn't too clear, so I've attached a spreadsheet that models the issue. Graph 1 is on the right, Graph 2 on the left.

Thanks in advance.
