different barcharts in one graphic with varying number of grouped bars

[Karin <twentestat@yahoo.com>]

Hello,

 

I am puzzling with the following figure:

I have four categorical variables with different numbers of levels. Next to that I have for each level of the four variables a mean outcome. Now I want to plot the means as bars, with the means of the levels of one categorical variables as grouped bars (so next to each other). And the grouped bars of the four categorical variables also next to each other.

Barchart only accepts a matrix, but since the numbers of levels differ I can not put them in a matrix. Does anyone know how I can achieve this?  

 

Thanks in advance,

 

Karin
