as is traditional in a KM plot (step plot) the symbol for a censored value is a ¦ (vertical line). every example Ive seen in GTL uses a symbol of plus as there doesnt seem to be an appropriate symbol and unlike old versions I cant use a capital i. My example below uses a + too and it doesnt look quite right.

stepplot x=_x y=_surv / group=signvar lineattrs=(pattern=solid) name='s';

scatterplot x=_x y=_cens / markerattrs=(symbol=plus) GROUP=signvar  ;

You have two option.  With SAS 9.4M1, you can use any character from a font as a symbol using the SYMBOLCHAR statement.  With Unicode fonts, your choices are huge.  Pre SAS 9.4M1, you can use the SCATTERPLOT with MARKERCHARACTER option to draw the vertical bar "|" at each location.

Hi Sanjay

Im using 9.3 and using the scatterplot/markerchar. however it doesnt give me the option to use a vertical bar "|", only the ones in the standard ones.

unless Im doing something wrong with my scatter?

scatterplot x=_x y=_cens / markerattrs=(symbol=plus) GROUP=signvar  ;

Thanks

Adie

after all this...my boss has changed his mind and the "plus" is now acceptable!

Thanks anyway!

OK.  But if you still need to do something similar later, here is what you do.  First, add a new column (censor) to your data and populate it with the character(s) you want to display in the graph.. In this case, put a "|" where ever you want the display the censor observation.  Then use the scatterplot with same X and Y variables and the option markercharacter=censor.  Keep the length of this variable (or format) as small as possible to avoid any leading blanks.
