The following terminal session opens a window in a small Java application and displays the results. -------------- Begin Mathematica session ----------------- Mathematica 6.0 for Mac OS X x86 (32-bit) Copyright 1988-2007 Wolfram Research, Inc. In[1]:= <<JavaGraphics` -- Java graphics initialized -- In[2]:= Plot[Sin[x]/x, {x,-2*Pi,2*Pi}, ImageSize -> 800]; -------------- End Mathematica session ------------------- You can also write your own display function that calls an external program. I suppose a logical external viewer on Mac OS X is Preview. Here's one way to set this up. -------------- Begin Mathematica session ----------------- Mathematica 6.0 for Mac OS X x86 (32-bit) Copyright 1988-2007 Wolfram Research, Inc. In[1]:= Developer`InstallFrontEnd[]; In[2]:= df[g_] := Module[ {strm}, strm = OpenWrite["!open -f -a /Applications/Preview.app"]; WriteString[strm, ExportString[g, "EPS"]]; Close[strm]; ]; In[3]:= $DisplayFunction = df; In[4]:= Plot[x^2, {x,-2,2}] -------------- End Mathematica session ------------------- Note that many commands involving Import/Export will start up a FrontEnd in the background; the first version using JavaGraphics does this, for example, as you can see using top. For some reason, this second version hangs without an explicit installation of a FrontEnd. Mark
