line graph, by() on different y-axis scales

[tim bradshaw]

Hi there

I'm plotting several graphs using the -line- command and the by() option.

* Example generated by -dataex-. To install: ssc install dataex
clear
input byte sex int year float rate
1 1999 0.5
1 2000 1.5
1 2000 2.0
1 2002 2.3
1 2003 2.5
1 2004 3.0
1 2005 3.4
2 1999 17.5
2 2000 22.5
2 2001 27.5
2 2002 32.5
2 2003 37.5
2 2004 42.5
2 2005 47.5
end

I like how Stata automatically scales the y-axes to fit the line graphs nicely when plotting each sex separately:

line rate year if sex == 1, yscale(range(0 .)) ylabel(#5)
line rate year if sex == 2, yscale(range(0 .)) ylabel(#5)

But when I use the by() function to plot the graphs side by side, the y-axes are the same for each graph:

line rate year, by(sex) yscale(range(0 .)) ylabel(#5)

Of course this is a sensible default, but for my purposes I would like each graph's y-axis to be scaled just as it is when plotting each sex separately.

Any tips on how to achieve this?

With many thanks

line rate year, by(sex, yrescale) yscale(range(0 .)) ylabel(#5)

brilliant - thanks!

Your data example doesn't, to me, rule out the possibility that logarithmic scale might help.
