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)

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
