I have some credit ratings for a company and they are
changing over time. Credit ratings are in the form AAA,
AA, A, BBB, BB, B, CCC, CC, C, with AAA being the highest
and C the lowest. I want to plot how the company's rating
has changed over time, but the data is non numeric. I want
the Y axis to show the rating, the X axis to show monthly
time over 5 years say, and a line graph showing the
movement of the rating through time. Does anyone know how
to do this?
