- rsnape/OpenMatlabFigureInOctave 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. To change the defaults, use the following on the .octaverc file.. Changing default figure size []. > On 27 May 2009, at 00:47, Xin Dong wrote: > >> Hi all, >> >> I use octave to produce figures for my paper. 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. The result is displayed in the Octave or Matlab command window. A very handy function that I've had to do some odd workarounds to get similar functionality in the past. In Figure 1 you can see a screenshot showing different elements that constitute the GUI editor: 1 and 2: Dialog windows in edition mode. 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 3: GNU Octave terminal to know results of the output variables produced as well as to send … Octave has powerful facilities for plotting graphs via a second open-source program GNU-PLOT. Figure 3 shows the frequency response plot for the 50,000 tap single stage filter. 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. I found the font size >> of the title is too small and I need to increase it. 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). Is there any way that I can set the >> font size of the title? As add-ons, we have used the grid(“on”) to show up the dotted grid lines, and print() to save the generated As of 2018b, Matlab has a new function, 'sgtitle'. The basic command is plot(x,y), where x and y are the co-ordinate. This can be changed though. The default size of a figure may be appropriate for simple figures but not so much when using subplot for example. However, it >> seems "-F:size" option only works with text in the figure but not >> the title and the axis labels. 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'. Long In this tutorial you will learn how to • plot data in Octave. Sometimes, Octave defaults are not the best for someone's specific use. A very simple .m file to read a .fig file and plot it in Octave. Since Rik changed the title: For me (with Windows 7) also maximizing doesn't trigger the repaint event (see the screenshot). Preferences []. It would be nice if Octave had it too. Line 13 generates the plot of the sum of the 3 trigonometric functions. 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.
