Sorry now with bottom post...

I have some serious problems with HomeBrew’s Octave 4.0.2, primarily with any kind of plotting. I’ve gone back to Octave 4.0.0_5, which works fine for me.

I don’t know what to report about 4.0.2 or where. Here is a typical problem:

~$ octave --no-gui
GNU Octave, version 4.0.2
…
octave> x = 0 : 0.1 : 4;
octave> setenv GNUTERM qt;
octave> plot(x, sin(x));
octave> 2016-05-15 17:03:39.865 octave-gui[11088:451929] modalSession has been exited prematurely - check for a reentrant call to endModalSession:

I am aware of plotting problems and I am currently trying to debug it. 
Does the problem already occurs while plotting or when printing?

Possible solutions:

(a) try the following (it makes sure that gnuplot is used)

octave-cli --no-window-system

graphics_toolkit gnuplot;
setenv GNUTERM qt;
x = 0:0.1:4; plot(x, sin(x));

Your instructions worked like a dream, Sebastian. Thanks!!!

Now with octave 4.0.2
   ~$ octave-cli --no-window-system
   GNU Octave, version 4.0.2
   ...
   octave> graphics_toolkit gnuplot;
   octave> setenv GNUTERM qt;
   octave> x = 0:0.1:4; plot(x, sin(x));
produces just what I've been getting with octave 4.0.0

And now, on a more substantial note
   octave> SPDRBND_plotACP90
produces the following graph of the performance of a dynamic ETF
