Plotting many curves

[Huaiyu Zhu]

Here're a few oddities about plotting I've noticed.  There should be
better ways of doing them:

1. When using "plot" each curve generates a separate file /tmp/oct-*. 
This seems very inefficient, especially if I want many line segments, like

|  |   || |  |    |
|  |   || |  |    |
-----------------------

axis ([-4 4 0 2]);
x = randn(10,1); y = zeros(size(x));
plot([x,x]',[y,y+.5]'); 

2. How to remove all the legends?  (Someone might have posted the answer a
short while a ago but I did not save it.)  How to make all the curves
solid lines?

3. It also seems that I can't draw more than 24 lines in this way (because
the legends would be out of page?).  In matlab I routinely draw thousands
of lines.

These might be due to the way octave interacts with gnuplot - but I can't
believe the famous gnu philosophy could coexists with such strict
limitations.
