How Y-axis scale number represent as percentage (for Kaplan-Meier curve graph)

[Ted Turov]

Kaplan-Meier curve.
1. How the Y-axis scale number represent as percentage with Graph Editor (I did not find it in Graph Editor)?
2. How to fix this in my STATA properties for any Kaplan-Meier curves? Thank you in advance!

// open example data
sysuse cancer, clear

sts graph ,                                       ///
    ylab(0 "0" .25 "25" .5 "50" .75 "75" 1 "100") ///
    ytitle("survival probability (percent)")

Maarten's advice is excellent as always. Nevertheless it may be worth flagging a general tool in this territory.

sysuse cancer, clear

* do this once 
ssc inst mylabels 

mylabels 0(25)100, myscale(@/100) local(myla) 

sts graph ,                                       ///
    ylab(`myla') ///
    ytitle("survival probability (percent)")

The idea behind mylabels (SSC) is that you specify the labels you want to see and the mapping that yields the scale Stata is using. For percents, there is no gain as the conversion is so easy, and indeed some loss in dependence on another command, but for other transformations there can be advantages.

To write code for representation in percentage?!
Graph Editor can not do this?!
I broke on this...
---------------------------
sts graph , ///
ylab(`myla') ///
ytitle("survival probability (percent)") [Enter]


. sts graph ,

failure _d: died
analysis time _t: studytime

.
. ylab(0 "0" .25 "25" .5 "50" .75 "75" 1 "100")
command ylab is unrecognized
r(199);

.
. ytitle("survival probability (percent)")
command ytitle is unrecognized
r(199);

I am sure Graph Editor can do this too, but I tend to avoid it whenever possible, and I suggest you do so to.

You wrote me privately you got an error message with the ///. It is better to ask questions publicly. Anyhow, that suggest you tried to copy the code in the command window. You should not do so. Instead you need to open the .do file editor, by typing doedit, paste the commands in there, and run it from there.
