st: Life Tables for Survival Analysis

["Donna Joseph" <donjoseph@hotmail.co.uk>]

Dear All

I am new to Stata.  I am using Stata 9 to try to draw a Life Table graph for 
a variable with 6 categories. The 6 slopes on the graph are shown by 
different, smooth, coloured lines which is great but I am not printing in 
colour.

I have tried the symbol command so that each line will be identified by a 
different symbol (i.e. dash, dot, long dash and dot etc).  However only the 
first symbol is recognised when I run the graph so I either have all lines 
with a dash, or all lines with a dot for all six categories.

I have looked in the Graphics and Survival manuals in addition to the 
searching the net but I cannot find an appropriate command which will allow 
me to identify the 6 slopes in black and white print. Can anyone help?

Unfortunately this mailer will not allow me to paste the graph so I have 
pasted the syntax below which demonstrates smooth curves and not steps 
(which I do not want).

# delimit ;
ltable durate work, graph notable survival noconf by(minus2) over 
yscale(range(0.4 1.0))
msymbol(i) yline(0.5, lpattern(dot))ylab (,nogrid);


Thank you

Don
