st: how to align the "baseline" (0) of 2 y axes?

Hi,
I am plotting bond and stock returns in Stata/SE 11.2 for Mac. Because
stock return are on a different scale some years, I had to plot them
against different y axes (and I could not even simply yscale(log) it
as sometimes the market went down…). But if I simply call for two
different y axes, the levels of zeros do not line up.
twoway (tsline close_bonds close_mortgage, ytitle("%", axis(1)))
(tsline return_close_stock, yaxis(2) ytitle("%", axis(2))), ///
legend(row(1) label(1 "Bonds") label(2 "Mortage bonds") label(3 "Stocks"))
I know the graph will be somewhat confusing because of the scale
change, but I would still keep the series in a single plot. How could
I make the zero levels line up (i.e. coincide on both the left and
right axis)?
Thank you,
Laszlo
