How do i change the Y axis on proc lifetest to percents?

[ShuliH]

Hello,

I am trying to change the Y axis from proportion (between 0 to 1) to percent (between 0% to 100%) on the proc lifetest without success. I understand how to use the proc template even in the Failure graph and managed to change the minimum, the maximum and the tickvaluelist of the Y axis on the next statement in proc template:

"

yaxisopts=(label="Probability to &XXX" shortlabel="Failure"
linearopts=(viewmin=0 viewmax=1 tickvaluelist=(0 .2 .4 .6 .8 1.0)))

"

but when I try to change it to:

"

yaxisopts=(label="Probability to &XXX" shortlabel="Failure"
linearopts=(viewmin=0 viewmax=100 tickvaluelist=(0 20 40 60 80 100)))

"

it changes the Y axis but the line of the graph ranges from 0 to 1.

 any suggestion on how to solve this?

I know that in the Gplot graph I can use the format for the Y axis. But it's not working here either...

I don't remember the variable off hand, but if it is Y, and it appears like this:Y=Y

Then change it to Y=eval(100*Y)

Thanks for the response,

in this graph the Y is calculated cumulatively from the cases that appear in the X so I can't use this option.

I'm not entirely sure on this one, but can't you simply edit the TICKVALUEFORMAT option instead of editing the actual values?

Correct me if I'm wrong @WarrenKuhfeld 🙂

@PeterClemmensen, that should work too!

Thank you!
it worked!

Good to hear, was not sure myself 🙂

I am having the same problem as the original poster, but I cannot get the TICKVALUEFORMAT option to work.

I want the y-axis of a KM survival curve to display percentages from 0 to 100%, in intervals of 10%.

I am not using gplot graph to make the graph, I am using proc lifetest.

I am using the following modifications to the %ProvideSurvivalMacros template:

%ProvideSurvivalMacros
%let yOptions = label="Survival (%)"
linearopts=(viewmin=0 viewmax=1
tickvaluelist=(0 .1 .2 .3 .4 .5 .6 .7 .8 .9 1)
tickvalueformat ??? );
%CompileSurvivalTemplates

proc lifetest data=mydata plots=survival(atrisk test nocensor outside);
time days * event(0);
run;

I don't know what to put in place of "???" after tickvalueformat to make it work

Any ideas??
