Displaying information from scatter plots

Hi,

Im sure this has already been answered, but if anyone could help any extra that would be great thanks.

My situation is as follows


Town______Population______ Shops
Uist_________3000___________ 4
Bradie______16000___________13
St Tom_____12500___________ 10

If I am displaying Population vs Shops in a scatter plot, how would I know which point is Uist or Bradie or St Tom? Without actually manually looking up the info. This would be easy for the example above but my data set has many hundreds of points therefore a look up process would be time consuming. I would like to be able to click a point on the scatter plot and see what town I am looking at, usually for outliers on the dataset.


Kind regards
Alistair
