Hi guys, i have a basic plot (plotting column 1 versus column 2)

eg



patient1 1 7
patient2 2 8
patient3 3 9
patient4 7 10
patient5 9 11



i make a scatterplot of these.(so my points are (1,7), (2,8), (3,9),(7,10),(9,11)). The labels on these points are patient1,2,3,4,5.


i have a list of interesting patients that i want to highlight:

interesting list:
patient 2
patient 3


i want these points on my graph to be labelled red, instead of the default.
But at i have about 20,000 patients (rows) and about 60 columns in my spreadsheet, i cannot do it manually....

Can this be done?
Thanks
Aoife
