plot time series on same time axis

[Chan Joo Jang <cjjang@xxxxxxxxxxx>]

Dear Ferreters:

How can I plot two time series with different time on same time axis?

For example, a variable t1 is defined on T=Jan-1900:Dec-1900, while
another variable t2 on T=Jan-0020:Dec-0020. Year is no matter. I would
like to compare monthly variations of these two time series.
Now I want to plot t1 and t2 on same time axis. How can I do this?

Many thanks in advance.
Jang.
