includes main-level programCreate a box and whisker plot, also called a boxplot. Then boxplot for a set of values displays the smallest observation, lower quartile, median, upper quartile, and largest observation. In our case symbols, mark each value shown and a line connects the lower quartile to the upper quartile (through the median, of course).
Examples
Run the main-level program at the end of this file:
IDL> .run mg_boxplot
Other file information
- Todo:
handle outliers: values 1.5 IQR (interquartile range, the range between lower and upper quartiles) or more below the lower quartile or 1.5 or more above the upper quartile; values beyond 3.0 IQR are "extreme" outliers
make horizontal boxplots
