I suggest you try the following.

Plot a scatter graph as normal with your first set of data.

Then to add more data to the scatter graph...

Right click on chart and select <Source Data and select the <Series tab.

Select <Add in the series dialog box and type in the relevant sections
opposite the cell references of your new x and y values. Your second set of
data will now appear on the chart. Just repeat to add a third series.

I hope this helps. Please feel free to write back if you are still having
difficulties and I shall endeavour to assist further.

Regards
