There currently isn't a built-in control for this, but the effect can be
obtained by replacing the entries in the output by reversed entries. 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.
