Many Thanks Dennis, The distributions are simulated ordinal data all bounded in the same upper and lower limit, and I wanted to plot how the distribution changes through time. Since the distributions are often multimodal boxplots were not useful so I made some violinplots... My practical solution which I'm testing right now is to create a matrix of frequencies and then plot these as a series of horrizontal barplots (after normalising each distribution) , using the offset parameter to control the temporal sequence....It actually works fine, but I was wondering if there were better ways...
