Credit Rating Graphs

[Artur Patricio]

Hello I would like to know If it is possible when doing a graph to assign alpha charecters to my y axis. I want to make a graph of the credit ratings of a country during time. I have already used the valmap function to attribute labels to my numeric values rating scale (i.e 24=AAA; 23=AA+). However when I do a graph on the y axis it still appears numbers instead of letters. Does anyone knows how to do this ?

Thanks a lot in advance for the help you might gave to me,

Artur

I believe that cannot be done.

Hmm... I have seen that on the graph options - Axes & Scaling - Obs/Date - add custom obs labels - you can assing the letters to your X axis but I guess that we can do the same for the y axis. or not ?

Cannot.

Hello again dear colleagues I just want to share with you the programming I have developed to solve my problem which was doing credit rating graphs. I discover a trick for doing such graphs. Below a share with you the commands I hope that it can be of help for the people that have the same problem.

%x="PT_RTG_SP"
%MYGROUP="GR_"+%x
%MYGRAPH="GRA_"+%x

group {%MYGROUP} PT_RTG_SP+0

Call graf_GR({%MYGROUP},240,%MYGRAPH)

{%MYGRAPH}.axis(left) range(10, 24)
{%MYGRAPH}.axis(left) -label grid zeroline
