Multiple plots above each other with common x-axis

[Petar Knezevich]

Hi,

Is it possible to stack multiple plots on top of each other with no
vertical space between them and display the x-axis only on the bottom
plot?  I would like to combine any number of plots in this manner
(e.g. 2, 3, 4 or 5 plots).

--------------------
|      plot 1     |
|                   |
--------------------
|      plot 2     |
|                   |
--------------------
Common X-Axis

Is there already an option in subplot to produce this result?
Currently I use a standard subplot configuration but there is too much
space between each plot.
