octave uses the powerful gnuplot as the backend of its plotting functionality. And in the frontend provides various plotting functions. Let’s look at the most beautiful ones. Basic 2D Plotting Chapter 3: Working with Octave: Functions and Plotting 65 Octave functions 65 Mathematical functions 66 Time for action – using the cos function 66 Polynomials in Octave 68 More complicated mathematical functions 69 Time for action – putting together mathematical functions 70 Helper functions 71 Generating random numbers 72 min and max 72 Using the Octave kernel with Jupyter notebook does not plot any figures. A cel containing the simple code : plot ([1,2], [3,4]) Octave-Forge - Extra packages for GNU Octave: If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca. Description when I plot some graphs, I want to have idea about the value of certain points. In Matlab exist the so called “datatip”: you click on a certain point of a plot, and appears a text inside the plot with the (x,y) coordinate of such point.

My code is x = [1,2,3,4]; y = [1,2,3,4,5]; z = [1,2,3,4,5,6]; for xi = 1:4 for yi = 1:5 for zi = 1:6 a(xi,yi,zi) = x(xi) * x(xi); endfor endfor endfor [xx yy zz] = meshgrid(x,y,z); scatter3(xx(:), yy(:), zz(:), [], a(:),'fill'); xlabel('x') ylabel('y') zlabel('z') colormap(rainbow) colorbar() Introduction to Octave Dr. P.J.G.

## Retain plot data and settings so that subsequent plot commands are displayed on a single graph. Line color and line style are advanced for each new plot added. hold all (deprecated) Equivalent to hold on. hold off. Restore default graphics settings which clear the graph and reset axis properties before each new plot command. (default). hold

You can add titles, axis labels, legends, and arbitrary text to an existing plot. For example: x = -10:0.1:10; plot (x, sin (x)); title ("sin (x) for x = -10:0.1:10"); xlabel ("x"); ylabel ("sin (x)"); text (pi, 0.7, "arbitrary text"); legend ("sin (x)"); The functions grid and box may also be used to add grid and border
The plot3 function displays arbitrary three-dimensional data, without requiring it to form a
The fmt format argument can also be used to control the plot style. It is a string composed of four optional parts: "

### I can't plot from Octave 4.0.0 in Ubuntu 14.04LTS, which I've just updated, The plot windows are created, but scrambled. Works fine on my Windows7 machine.

Lines for contour plots are generated with an Octave function, so contour plots are now 2-d plots instead of special 3-d plots, and this allows you to plot additional 2-d data on top of a contour plot. GNU Octave A high-level interactive language for numerical computations Edition 4 for Octave version 4.2.2 March 2018 Free Your Numbers John W. Eaton Octave Packages. GNU Octave can be extended by packages. Find them at: Octave Packages; Octave Forge; Development. Octave is free software licensed under the GNU General Public License (GPL).Assuming you have Mercurial installed on your machine you may obtain the latest development version of Octave sources with the following command: I do in Octave in a terminal with Sixel Graphics: t=[0:0.1:6.28]; plot(t,sin(t)) Nothing is output.

To start Octave type the shell command octave, double-click Octave.app or whatever your OS needs.
