Re: X-Axis title in X-Log plot.

Yi,

The problem is that you are trying to panel two plots that are not the
same size. gsn_panel should only be used on two plots that are the
same or very close to the same size, otherwise you will get unexpected
results.

What's happening is your first plot is much larger than your second
one, and is pushing the second too close to the bottom of the unit
square that NCL draws in. Hence, you can't see the bottom label.

Instead of using gsn_panel, use the vpXXX resources to position and
resize the plots yourself. See example 20 at:
