The following shows how that could be done. In[1]:= << StatisticalPlots` In[2]:= sldata = {1, 3.2, 3.1, 4.556, 5.7345}; In[3]:= slp = StemLeafPlot[sldata]; In[4]:= slp[[1, 1, 1, 1, 2 ;; All]] = Reverse[slp[[1, 1, 1, 1, 2 ;; All]]]; In[5]:= slp Out[5]= Stem Leaves 5 7 4 6 3 12 1 0 Stem units: 1 Is this a common thing to want for stem and leaf plots? If so, perhaps it would be useful for us to add an option to the function. Darren Glosemeyer Wolfram Research
