Customizing axis and legend labels in a MACRO %KM_TTE_MIANALYZE

Hello,

I have survival analysis data where I have imputed some missing values with PROC MI/PROC MIANALYZE. To produce a KM plot based on the imputed data, I am using the MACRO %KM_TTE_MIANALYZE. The macro works however it produces labels TREATMENT 1,0 and x and y axis labels I do not want for publication. I have tried to use the %ProvideSurvivalMacros that I use to customize standard KM plots produced using proc Lifetest but it does not work. In the macro I do not even see the works axis or label. I am wondering if anyone has any advice or could recommend a different MACRO or procedure to produce KM plots for multiple imputed dataset where labels and axiss can be edited.

thank you

At a guess you need to find the definition code for the PLOTSTEP macro called towards the end of the code:

%if "&plot"="yes" %then %do;
			%plotstep(plotdata=_tmc_allsp, xvar=timelist, yvar=Survival_comb, by=%str(&by &strata), trtvar=&trtvar,
			outfname=&plotfname, outpath=&plotpath);
		%end;

The name Plotstep coupled with the condition makes me think that contains the actual plot code. Since the macro appears to use a data set created for plotting the plot may well not involve Proc Lifetest at all. So the %KM macros may not affect other code. Or Plotstep has it's own calls to the %KM macro variables that would override anything set prior the execution of the Plotstep macro.
