boxplotPerc
PURPOSE: A boxplot function which allows users to specify the percentile
values of boxplot whiskers while still using the standard MATLAB boxplot options.
INPUTS: Use syntax exactly as with the standard "boxplot" command, but
with a scalar or vector of percentile values as the second input.
data - a data matrix as with normal boxplot
percentile - a vector of 2 percentile values [lower, upper],
specified as percentages --OR-- a single scalar indicating the
desired span of percentiles. If the scalar is used, the program
solves for the necessary [lower, upper] values.
Examples: [5 95] or equivalently [90]
[2.5 97.5] or equivalently [95];
varargin - all the remaining boxplot options, according to the
typical MATLAB syntax.
OUTPUT: a boxplot with the whiskers set to the specified percentile or
percentile range values.
EXAMPLE: Here is a highly asymmetric data set along with a call to the boxplotPerc function:
data = normrnd(-1,1,100,5).^3;
boxplotPerc(data,90, 'notch','on','symbol','o','Widths',[0.1:0.1:0.5])
