Works for me as well on Windows XP 32bit.  Since we can't reproduce this we can't debug it.  Closing report.

Trying with ".^" goes better and then the plot appears fine with qt and with gnuplot.
Using gnuplot it appears within a second.

Note: the first plot (with qt) took quite a bit of time. As gnuplot is slower than qt, you might try just a little more patience.

Hmmm,  I get this (with octave-4.0.0 in Win7 64bit):

>> x = linspace(0,100,100);
>> y = x^2
error: for A^b, A must be a square matrix. Use .^ for elementwise power.

-verbatim

Trying with ".^" goes better and the plot command just works then with gnuplot and Qr, the plot appears in < 1 second for gnuplot.

x = linspace(0,100,100)
y = x^2
plot(x,y)
