KM-curve failure plot and modifying the y-axis

ChrisMac — Mon, 17 Aug 2015 20:42:44 GMT

Hi,

I am creating Kaplan-Meier curves by using the PROC LIFETEST statement. To modify the y-axis, I modify the survival template and create macros as described here:

http://support.sas.com/documentation/cdl/en/statug/63962/HTML/default/viewer.htm#statug_templt_a0000000062.htm

However, these macros do not affect any graph that uses graph templates other than those described in the link. This means that these macros cannot be applied when creating a failure plot instead of a survival plot. I want to create failure plots (by using PROC LIFETEST and plots=survival(failure)) and change the y-axis.

How do I find the failure plot template and how should it be modified?

Thanks!

You can modify your failure plot template similarly.

Run the proc with ODS TRACE ON and look at the output in the log. It will let you know the template for the failure plot.

For example, this is the template for the survival plot:

Stat.Lifetest.Graphics.ProductLimitSurvival

Change the template name in the macro code and then your changes will follow through

Thanks for the quick reply! 🙂

The template is called: Stat.Lifetest.Graphics.ProductLimitFailure
