Assume there are three nominal variables, A, B and C.
It is easy enough to produce a clustered bar chart with two of them: one, e.g. A, goes into the "X-Axis" and one into the "Cluster on X", e.g. Z.
There are also 3-D versions of this where one can add a "Z-Axis" and use a third nominal variable. But those are very hard to read since some bars will be hidden behind others.
Is there a way to create a 2-D clustered bar chart which groups two nominal variables on the "X-Axis". So say, I want to have variable A and B on the "X-Axis". So I would like to have for each value of A a clustered bar chart with each value of B. For example, say A is sex (say male and female) and B is eye color (say brown, green, blue). Then I would like to have for male a bar with all the male brown eyed, male green eyed, and male blue eyed. And right next to it in the same chart should be the next group of females: female brown eyed, female green eyed, female blue eyed.
