Thanks for the hints about contour.m.
When I try to make a contour plot I cannot make more than 10 levels. I
have been looking in the code and I think that the problem occurs because
of a maximum string length. In order to prove this, I copied contour.m to
my home directory and removed two semicolons. Afterwards line 88 - 96
looked like this:
if (is_scalar (n))
command = sprintf ("gset cntrparam levels %d", n);
elseif (is_vector (n))
tmp = sprintf ("%f", n(1));
for i = 2:length (n)
tmp = sprintf ("%s, %f", tmp, n(i)) # colon is removed
endfor
command = sprintf ("gset cntrparam levels discrete %s", tmp) # same here
endif
I tried the following
octave:1> x = y = [0:0.01:2];
octave:2> z = sin(x' * y);
octave:3> contour(x,y,z,[1:1:15])
The resulting plot contained only levels 1:10. Here is the output. Note
that for i>10, I got tmp = 1:10,N.
tmp = 1.000000, 2.000000
tmp = 1.000000, 2.000000, 3.000000
tmp = 1.000000, 2.000000, 3.000000, 4.000000
