I have been using the __gnuplot_set__ xtics command
for a long time to set non-uniform ticks on the x
axis, particularly handy in marking x-intercepts.
The new version of Octave 3.0.0.0 does not support
this method. Does anyone know how to do this?
here is a sample program that I have used for many
years to teach xtic setting:
xmin=0.0;
xmax=2*pi;
ymin=-1;
ymax=1;
deltax=(xmax-xmin)/200;
axis([xmin xmax ymin ymax]);
x=xmin:deltax:xmax;
y=sin(x);
plot(x,y)
__gnuplot_set__ xtics ( "Pi/4" pi/4, "Pi/2" pi/2, "Pi"
pi, "3*Pi/2"
1.5*pi, "2*Pi" 2*pi )
plot(x,y)
I already tried the suggestion on my PC Windows Vista
with Octave 3.0.0 installation, and the
set (gca, "xtick", [pi:pi/2:2*pi]);
command does not change the default tickmarks.
I am a teacher at a small college, and it would really
help my students label their graphs and check handwork
if I could get the NON-uniform tick setting working
again.
Any suggestions welcome.
ps. My question does not appear on the octave help
page... how can I post this question there for
everyone to see?
thanks!
