Default black and white plot. Explicitly creates ut axis in DAYS.
cnLineLabelPlacementMode = "constant", is one of the
for controlling contour labels. the constant method is the only one in
which the label becames part of the line.
I only have TN data to demo in these scripts. For data that has both
positive and negative values, there are numerous
contour effects you can use to enhance your plot.
There are four title strings you can use to label a plot. The
automatically labeled with the long_name of the data, and
labeled with the units of the data. These can both be overwritten, or
turned off (by setting them to ""). There is also

Adds color and a local time axis. Explicitly creates ut axis in HOURS.
cnFillOn = True, turns on a color plot.
a special resource that tell the plot template to use the full range of
There are many built-in
to choose from and many ways of specifying the
color of a plot.
axis.ncl contains all the
functions used to put local time axis on the HAO
master scripts. We have used one of
those functions here (set_lt_axis_utplot). To use this function, you
need to load axis.ncl at the top of your script. Note that this function
We add the extra text on this plot using
gsn_text_ndc. You can learn more about adding text to a plot
from the CCSM
text example page.
Demonstrates limiting the y-axis, calculating a zonal mean.
Explicitly creates ut axis in MONTHS.
trYMinF will limit the lower bounds of the y-axis.
There is also a
The NCL built-in function
dim_avg is useful for calculating zonal averages. You should be aware,
however of the
consequences on meta data of any computation. Because of this
we have chosen to use the
wrapper version of the function.
Demonstrates a panel plot. There are too many nuances associated with
panelling. Please review the CCSM panel example page for details.
cnLevelSelectionMode = "ManualLevels"
are the resources that manually sets the contour levels.
How to add the min/max to a plot and stretch its aspect ratio.
vpHeightF will allow you to stretch a plot.
The NCL built-in functions
max allow you to take the min and max of the data.
