the plot interface that creates a contour plot.
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.
ZeroNegDashLineContour is the special
shea_util.shtml function that will take contours and make the
zero line double thickness, and the negative lines dashed. There
are many other
contour effects you can use.
There are four title strings you can use to label a plot. The

labeled with the units of the data. These can both be overwritten, or
turned off (by setting them to ""). There is also

color of a plot.
axis.ncl contains all the
functions used to put local time axis and height axis on the HAO
master scripts. We have used two of
those functions here (set_lt_axis_cnplot and haxis). To use these
need to load axis.ncl at the top of your script. Note that
set_lt_axis_cnplot turns off
Demonstrates manually setting contour intervals
cnLevelSelectionMode = "ManualLevels"
are the resources that manually sets the contour levels.
vpHeightF will allow you to stretch a plot.
Demonstrates a panel plot. There are too many nuances associated with
panelling. Please review the CCSM panel example page for details.
Demonstrates how to calculate the min/max of the data and put it on a plot. Also
limits the y-axis.
The NCL built-in functions
max allow you to take the min and max of the data.
trYMinF will limit the lower bounds of the y-axis.There is also a
Interpolates to height.
hao_contrib.ncl contains the
the function (zplev_to_height) used to interpolate a variable on the HAO
master scripts. To use this function, you
need to load hao_contrib.ncl at the top of your script.
This functions requires that you set a bottom and top height level to
interpolate to and the interval between the top and bottom.
