According to the link below a hammock plot is generalization of a parallel coordinate plot where the lines are replaced by rectangles that are proportional to the number of observations they represent. This plot is different from both the traditional parallel coordinate plot and the hammock plot since the category's width is proportional to it's activity, not the line width. Maybe it's type is still unnamed. http://www.schonlau.net/publication/03jsm_hammockplot.pdf http://www.schonlau.net/publication/03jsm_hammockplot.pdf
