Re: NCL 5.1.1 Font problems

Hi Arnold,

Thanks for sending the images. This really helps.

------------------

First, I noticed you have times-roman fonts. It looks better if you use helvetica.
If you have a ".hluresfile" in your home directory, you can configure all of your
fonts to be helvetica easily. For more information, see:

http://www.ncl.ucar.edu/Document/Graphics/hlures.shtml

------------------

Second, I noticed that your "90oW" label on the rightmost plot is falling
off the edge. This may again be due to the fact your plots are not the same size.

In the gsn_panel call, you can force the rightmost plots to be a little further
to the left by setting the gsnPanelXF resource. See example 19 at:

http://www.ncl.ucar.edu/Applications/panel.shtml#ex19

for more information.

--------------------

The original issue is that you are paneling plots that are not the
same size. Your leftmost plots have tickmarks, and your rightmost plots don't.

The "60oN" label at the top of your left Y axis actually goes slightly above the
top Y axis line, which causes any titles above it to be automatically adjusted a
little higher. This is why the labels are higher on the leftmost plots than
they are on the rightmost plots.

I think the easiest thing to do is "fake" NCL out and make it think it has labels on the left axis
on the rightmost plots. You can do this by going ahead and drawing the labels did you did
for the lefmost plots, but draw them in white so you can't see them:

    res@tmYLLabelFontColor = "white"

Let me know if this doesn't work.
