How to make x-axis and y-axis meet at (0,0) using proc lifetest

[SeaMoon_168]

I use Proc Lifetest to create KM curves by using SAS macro but I cannot find a easy way to make x-axis and y-axis meet at (0,0) to the bottom left corner using lifetest and sas macro. I would not use sgplot to make it. Many thanks.

Search for

%let yoptions=

and 

%let xoptions=.

You will see several examples and general info.

Next, look at page 899.

Now try to modify the example to specify offsetmin= instead of the options in that example.

Thank you for your reply. 

I added offsetmin=0 to xOptions and yOptions. Then y-axis starts from 0 a the bottom left corner but x-axis still does Not start from 0 (shown below).

Hi @SeaMoon_168,

The following code, copied right out of the guide linked by @WarrenKuhfeld, works for me in SAS Enterprise Guide 7.15 HF8 (7.100.5.6214) (32-bit). If it still isn't working for you, you might need to provide more details.

if pre then put _infile_;
if index(_infile_, '<pre>') then pre = 1;

%inc 'macros.tmp' / nosource;


%ProvideSurvivalMacros

%let yOptions = offsetmin=0;
%let xOptions = offsetmin=0;

%CompileSurvivalTemplates

proc lifetest data=sashelp.BMT plots=survival(cb=hw test) notable;
  time T * Status(0);
  strata Group;
run;

That code produces the following output.

Thank you for your reply. Shall I just copy and use the same code between "ods graphics on;" and "%CompileSurvivalTemplates" without any changes? But it does not work ...

[mtnbikerjoshua]

Can you post example code that will reproduce the problem?

[SeaMoon_168]

Here is my code with adding your code at the beginning. Thanks.

Apologies for not responding. I ran your code with the following proc lifetest at the end, and the axes still came out as desired. Did you ever figure out the issue?

data toplot;
  set sashelp.BMT;
  T = T / 200;
run;

proc lifetest data=toplot plots=survival(cb=hw test) notable;
  time T * Status(0);
  strata Group;
run;
