Thanks!

I already try'it that but seem to be an bug. My plot show an intrerupted line and old axis don't disspear.
I use octave 3.2.1 on Ubuntu 11.04. Plots are rendered with gnuplot.
I put an image as attachament to see what i mean.

It works correctly for me. Perhaps we're doing something else differently that it producing a different result?

The following works for me.

close all

clear all

x = 0:0.1:10;

y = sin(x)./(1+x) + x*01 - .4;
plot (x, y);

set (gca, "xaxislocation", "zero")

print test.png
preview test.png

Does this work for you?

Ben

Ben,
please add the line

set (gca, "box", "off")

to see the remainding of the axis. This problem is even in the plot "polar" when the box is switched off.

Indeed,
I posted this issue it in the help mailing list a few days ago

http://octave.1599824.n4.nabble.com/Axis-issue-td3887910.html

 

This may be a feature of gnuplot.

If you'd like to experiment with gnuplot to see if the horizontal line at the bottom can be suppressed, you can save the gnuplot plotstream by ...

drawnow ("png", "debug.png", false, "debug.gp")

Then run gnuplot and type ...

load "debug.gp"

Each time you load "debug.gp" the file "debug.png" will be saved. You can try modifying the gnuplot commands in gnuplot.gp to get the desired result. If you're successful, I should be able to modify Octave's sources to fix this.
