As the boxplot code does not use a gsn drawing function to construct the boxplot, note that the resources gsnLeftString, gsnCenterString, and gsnRightString will not work with the boxplot function.
Boxplots

Note: You must load
shea_util.ncl
to use the boxplot function.
box_2.ncl:
Demonstrates how to set the color and line thicknesses of individual
box plots. gsLineThicknessF will set the line thickness of the boxes.
boxWidth and boxColors are function local resources that allow you to set width and color of the boxes.
box_3.ncl:
Adds some polymarkers.Uses gsn_add_polymarker (added NCL version 4.2.0.a012) to put the polymarkers on the plot. Recall that this a function that must be set to a dummy variable which is never deleted before the plot is created.
box_5.ncl:
Shows how to calculate and plot the median, minimum value, maximum value, and the 25th and 75th percentiles of two
timeseries.
