Plotting lines and data points on scatter chart

I'm trying to produce a chart that has both actual data values from a database and matching "line of best fit" plots on the one chart. I have 4 data series, 2 of the actual data values and 2 that represent the values for the "line of best fit". What I want to do is:

Plot the actual values just as data points (joining them with lines in meaningless) and Plot the "line of best fit" values as a line.

When I edit the data series on the scatter chart, I can see the "Plot data as line" option but it is "greyed" out.

Have I missed something really simple here or is this not possible. I'm using RS2005

Many thanks
