How do I format x axis values in proc sgplot?

lousam — Fri, 22 Jun 2018 19:58:12 GMT

Hello,

I am trying to create a graph where the x axis will be time CD4 count was measured (before diagnosis, at diagnosis, 2 months after diagnosis, 4 month after diagnosis, 8 months after diagnosis and 10 months after diagnosis) and y axis will be the CD4 count. I want to label the grid values so that I can see: "before diagnosis", "2 months", "4 months" and so on on the x-axis. The partial code I want to use is below. How do I achieve the formatting of the "Time of CD4 measurement" values in the graph?

proc sgplot data=one;

panelby state;

refline 0/ axis=x lineattrs=(color= red pattern=2);

series x=time y=CD4_count lineattrs=(color=gray pattern=1 thickness=1);

colaxis label= "Time of CD4 measurement" grid values= (0 to 10 by 1);

rowaxis label= "CD4_count"; run;

I appreciate any help you can offer

A user defined format works fine.

Assuming you had used numbers instead:

proc format;
value time_measure_fmt
 1 = 'Before'
2  = 'At'
3 = 'After';
run;

Then apply it in SGPLOT

format time time_measure_fmt.;

Thank you. Sorry, I made a mistake I meant to use procsgpanel in my question. I am using a macro where my data set varies (4 data sets total) but the variables and the code remains the same as the one I listed in the previous question. For some reason using the format statement isn't working (can't see the formatted time values). Thank you again

1) don't see a FORMAT statement in the Proc SGPLOT/ SGPANEL code.

If the format is not permanently associated with the variable you need a statement such as

Format time <formatname.>;

2) We would likely need to see actual values of X and your format definition to diagnose anything further.
