v.faultdirections draws a polar barplot of fault directions, with values binned according to the step parameter. Directions have to be stored in an attribute column of the vector map containing the faults.
The parameter legend_angle allows positioning the radial axis. By setting the flag a the user can choose to display absolute number of lines as radial axis labels instead of the default percentages.
The plot can be saved to a graphics file interactively from the matplotlib window.
