Humm. I don't see any axes in that plot. Just lines. Maybe
what you are looking for is PLOTS, not AXIS.

I'm just leaving my office (for about 5 weeks), so I probably
can't help much. If I wanted a single x-axis for three plots,
I would draw the first plot with XSTYLE=8, the second and
third plot with XSTYLE=4, and then put the final axis on
top with AXIS, XAXIS=1 after I drew the 3rd plot.
The Y axis is more problematical, but I illustrate one way
to handle it in the article I had you read.
Vertical lines can be drawn anywhere and anytime with PLOTS.
Cheers,
David

Thanks, David. I checked your code. The two figures are
plotted in the save plotting area. What I hope to do is to
plot the lines one box after another box. Some thing like
this:
www.engin.umich.edu/~xcai/test_stack.ps
Here, I plotted stackplot of sin(x), cos(x) and cos(x). The
plotting area is different for each plot. I want to add xaxis
fot the whole figure. By the way, can I add one vertical line
for the whole figure? Right now, I add the vertical line in
each box seperately. I really appreciate your help.

Once you execute a PLOT command the "data" coordinate
system is established. So now you can issue an AXIS command
and the command will know where to draw the plot. I seriously
doubt whether you want to be doing this in normalized
coordinates, as you are here.
Your code will look more like the code in this article:

Thanks for your quick reply! It becomes easy with deleting axis
between figures now ( I can not believe how easy it is : o ). But
how about if I want to add xaxis and yaxis for the stackplot? I failed
by doing this:
------------------------------------------------------------ ------------------
;How can I use 'norm' in axis?
axis, xaxis=0,0,0,/norm
axis, xaxis=1,0,1,/norm
axis, yaxis=0,0,0,/norm
axis, yaxis=1,1.0,/norm
------------------------------------------------------------ ------------------
Thanks again!

Oh, yes, there are *much* better ways. :-)
Here is an example of a "stacked" plot:
http://www.dfanning.com/graphics_tips/ladder_plot.html
You can turn off the XAXIS with XSTYLE=4. Or turn off box
axes with XSTYLE=8, etc.
