A very handy function that I've had to do some odd workarounds to get similar functionality in the past. The basic command is plot(x,y), where x and y are the co-ordinate. Figure 3 shows the frequency response plot for the 50,000 tap single stage filter. Octave has powerful facilities for plotting graphs via a second open-source program GNU-PLOT. It would be nice if Octave had it too. The default size of a figure may be appropriate for simple figures but not so much when using subplot for example. www.dm.unibo.it/~achilles/calc/octave.html/Multiple-Plot-Windows.html Fig 3. Attached at the bottom of this post is an example of octave code that I use to control the size of my figure window, positioning of the axes box, axis limits, etc. In Figure 1 you can see a screenshot showing different elements that constitute the GUI editor: 1 and 2: Dialog windows in edition mode. 3: GNU Octave terminal to know results of the output variables produced as well as to send … It creates a single title centered at the top of the figure for a plot window with subplots, which could have their own separate titles via 'title'. GNU Octave Scientific Programming Language. However, it >> seems "-F:size" option only works with text in the figure but not >> the title and the axis labels. CONCLUSION A very simple .m file to read a .fig file and plot it in Octave. Getting the bounding box change back to Octave figure properties is one of those things that could be accomplished with sending the core a "set()" command, if such a thing existed. As of 2018b, Matlab has a new function, 'sgtitle'. Since Rik changed the title: For me (with Windows 7) also maximizing doesn't trigger the repaint event (see the screenshot). Long In this tutorial you will learn how to • plot data in Octave. The result is displayed in the Octave or Matlab command window. This can be changed though. Sometimes, Octave defaults are not the best for someone's specific use. Note the usage of subplot(), taking the matrix dimensions (row, column) and the plot number to create the matrix of plots.In the example above, it created a 2×1 matrix of plots. Powerful mathematics-oriented syntax with built-in 2D/3D plotting and visualization tools; Free software, runs on GNU/Linux, macOS, BSD, and Microsoft Windows; Drop-in compatible with many Matlab scripts I found the font size >> of the title is too small and I need to increase it. To change the defaults, use the following on the .octaverc file.. Changing default figure size []. Line 13 generates the plot of the sum of the 3 trigonometric functions. Preferences []. octave:11> figure; octave:12> hold off; octave:13> plot(x, a+b+c); Line 11 creates a new graph window and line 12 tells Octave that any subsequent plots should simply replace previous ones. > On 27 May 2009, at 00:47, Xin Dong wrote: > >> Hi all, >> >> I use octave to produce figures for my paper. The single stage 50000 tap comparison filter has a much longer processing time – compare this with Figure 2 (both run in Octave on Windows 10).
