superimposing histograms con't
Earlier, I posted the following question:
I want to superimpose histograms from three populations onto the same graph,
changing the shading of the bars for each population. After consulting the
help files and the archives I cannot find out how to do this (seemly)
simple graph. To be clear, I want
- a single x axis (from -3 to 18)
- three groups of bars forming the histograms of each population
