Re: st: How to change scale of yaxis from proportion with lots of decimals to per 100000

I have tried no 3 method. I still have problems. I have made a twoway
graph with a by statement which produces 4 graphs with different
yscales - no1 is from 0.00005 to 0.00015, no2 is from 0.0005 to
0.0025, no 3 is from 0.01 to 0.04 and no4 from 0.01 to 0.1. I want to
multiply all by 100,000.
I have individual data for about 2,000,000 infants and want to use the
original dataset. I tried the following command

twoway fpfitci nec ar,  by( pmatur, rescale legend(off)
l1title("Incidence rate per 100,000 live births")) xlabel(1985 1990
1995 2000 2005 2010)  ylabel(0.00005 "5" 0.0001 "10" 0.00015 "15")

gives the correct result for one of the graphs. I tried the following

twoway fpfitci nec ar,  by( pmatur, rescale legend(off)
l1title("Incidence rate per 100,000 live births")  y1label(0.00005 "5"
0.0001 "10" 0.00015 "15") ) xlabel(1985 1990 1995 2000 2005 2010)

but got error message that y1label was not allowed.

How can I make different ylabels for each graph?
