Hi everybody, I just installed a trial of Mathematica 7.0.1 to see how it improved from the previous Mathematica 5.2 that I still had. Slightly disappointing is the fact that the MathKernel does not output graphics anymore, that is, > ~/bin/math Mathematica 7.0 for Linux x86 (64-bit) Copyright 1988-2009 Wolfram Research, Inc. In[1]:= Plot[x^2, {x, -1, 1}] Out[1]= -Graphics- In[2]:= Without popping up a new window with the graph as it used to in Math5. $DISPLAY is set and valid. Even when I forcibly unset it, there is no warning from the graphics output subprogram (that used to start in Math5) that DISPLAY is empty. I found this [ http://tinyurl.com/yfn47x2 ] thread in this newsgroup archive mentioning similar issues; however, if directing MathKernel to output in StandardForm or TraditionalForm, the -graphics- won't be a -graphics-, but a point list and parameters of the plot (I'd really prefer the drawn plot ;) In[2]:= StandardForm[Plot[x^2,{x,-1,1}]] Out[2]//StandardForm= >GraphicsBox[... lots of text ...] What could be up with MathKernel7 that it produces no Graphics? With the graphical interface (~/bin/mathematica), plots are in fact shown, but I really prefer running just the MathKernel CLI. thanks, Jan
