I have a 8x10 matrix. 10 are the number of subjects and 8 the number of different ranges of values I have. I only have values of 1 or 0. I'd like to plot on the y-axis the 8 ranges and the x-axis the 10 subjects: i.e. i want to draw one bar for each subject, divided in 8 parts (in correspondance to the 8 ranges on the y-axis) and color these 8 segments black when it is 0 and white when it is 1. I attached a picture of the graph I drew by hand..
does anyone have any idea how i could do this?
Thanks in advance
