I see your point, and my first guess is that you are asking for something which, if not too difficult, it takes a lot of labor, and may not be worthwhile. A single graphics object has to be constructed out of two different ones, in order to attain that "translucency" you want. When you use Show[a1,a2] to display two plots, even with colors that look very transparent, a1 overrides whatever happens to be beneath. But I wonder if the following appoach could be useful to you: In[1]:= <<Graphics`Graphics`; <<Statistics`ContinuousDistributions`; <<Statistics`DiscreteDistributions`; <<Graphics`FilledPlot`; In[3]:= bern=BinomialDistribution[10,0.5]; norm=NormalDistribution[6,Sqrt[2.5]]; In[5]:= bc=BarChart[Transpose[{Table[PDF[bern,j],{j,0,10}],Range[0,10]}], BarStyle->GrayLevel[0.9],DisplayFunction->Identity]; In[6]:= fp=FilledPlot[PDF[norm,x],{x,0,11},DisplayFunction->Identity]; In[7]:= Show[fp,bc,DisplayFunction->$DisplayFunction]; This, I'm afraid, is as good as it gets, unless you want to do a good deal of tampering with the graphics objects.

Subject says it all. I'd like to have translucent colors, so that I can see one object underneath another. Is there any way to do this in Mathematica? For example, I'd like to plot a bar chart of e.g. a binomial distribution and overlay it with a filled plot of the corresponding normal distribution--but still be able to see the bars, underneath. --Ron Bruck -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
