I have two lists of data that i need to graph. An example is given below.

Project Ref Investment/Beneficiary in $ Efficiency Rating
1 87.3 2.3
2 156.6 3.8
3 185.8 3.8
4 8250.0 3.0
5 1164000.0 1.8
6 1500000.0 2.1
7 2812000.0 1.6
8 21462700.0 1.7

The Efficiency column represents the results of a survey on quality using a
rating scale of 1-4 with 1 being poor and 4 good for each project. We now
want to graph the relationship of efficiency with the investment per
beneficiary that each project received.Ideally we want our data in a matrix
with the Project references as data labels. This will help us identify
projects with lets say high Investmement and poor efficiency. Because the
scales are so different (refer to project 8 compared to the others) we
thought it would be easier to apply the same scale 1-4 for the
Investment/Beneficiary results. How do you apply a rating scale to a list of
numbers so that "proportional" representation is ensured? Is this the right
thing to do with the data above?
