I'd like to overlay two plots in quantmod. Use the wider time period only
for the axes. *(Or rather,* xmin= min(t1_min, t2_min); xmax= max(t1_max,
t2_max)*.)*

This question was asked a little over two years ago and answered two
ways: 1<https://stat.ethz.ch/pipermail/r-sig-finance/2009q2/003982.html>
2 <https://stat.ethz.ch/pipermail/r-sig-finance/2009q2/003985.html>. The
second answer requires editing quantmod internals (something I'm not
comfortable doing) and in any case Jeff Ryan may have improved quantmod in
the intervening period.


Jeff asked in his response *1* why anyone would want to overlay two time
series. In my case, I'm making a report for a client and I want to juxtapose
the client's returns vis-à-vis the S&P. It would also be nice to be able to
plot 2-3 series on top of each other for visual study.


Cheers to all who volunteer help on this list.
