Sample 43910: Customize the axis range of a survival plot
 |  |  |  |  |  |
This sample illustrates how to change the range of the X and Y axis on a survival plot that is produced with ODS Graphics and PROC LIFETEST.
See the LINEAROPTS= option within the YAXISOPTS= and XAXISOPTS= options in the LAYOUT OVERLAY statement in the Stat.Lifetest.Graphics.ProductLimitSurvival template for the syntax.
Please note that SAS/GRAPH® and SAS/STAT® are required in order to run this sample program.
