[ncl-talk] Smoothing option and graphics question

[Mary Haley]

Pallavi,

If by the "black portion" you mean the line contours, then there's not
really a resource to smooth line contours. You can look at our "smth9"
function, and there's an example at:

http://www.ncl.ucar.edu/Applications/lat_time.shtml#ex1

Regarding the squeezed plots: this is what I was trying to point out in the
lab, that you had asked to have a certain width and height of your plot,
but this causes your map plot to be skewed, which you generally don't
want.  If you don't set the mpShapeMode resource at all, then you will get
a non-skewed plot.

Regarding why the "title is on top".  I assume you mean that it is very
close to the edge?  If so, then yes, this is caused by using the "-trim"
option. This shouldn't be an issue, because while it is very close to the
edge, it shouldn't be cutting anything off.  You can try leaving "-trim"
off, and see how this looks.

To specify two titles, you can set a carriage return in the middle of your
title, using the special "~C~" syntax:

res_U at txString          = "Monthly Average Aerosol~C~Optical Depth AOD @
550nm"

This will cause the title to look like this:

Monthly Average Aerosol
Optical Depth AOD @ 550nm

So you might need to add some spaces to the first part if you want it
centered:

res_U at txString          = "   Monthly Average Aerosol~C~Optical Depth AOD @
550nm"
