These examples all use the compare prefab. All of these examples are included in the distribution (./pltestsuite/testpf_compare). Gallery of ALL prefab examples

The compare prefab computes means and standard deviations from your data set, and then displays them as a collection of bars with error bars.


Examples 1 thru 5 use the dexa.dat data file which looks like this (sample). Field 1 identifies the category, and field 2 (sex) identifies the subcategory. The other fields are variables that can be plotted.
