Boxplots differences

Compose the classic MATLAB boxplot with included between-group differences shown as lines with stars above.

Usage

In a given figure environment call

boxplotdifferences(data, groups, diffs, labels)

where the parameters are:

• data: the data in the same format as classic boxplot
• groups: group identifiers in the same format as classic boxplot
• diffs: (MxN double matrix) info about the significant differences. Each row represents a single difference. First column is the position of the group A, second column the position of group B and third column is the degree of significance (1 - '*', 2 - '**', 3 - '***'). Example:

diffs = [1 3 1; 1 4 2; 3 4 3];

• labels: group labels to appear in the boxplot in the same format as a classic boxplot. Example:

labels = {'group a', 'group b', 'group c'};
