GNU Octave

Time for action – making an inset

1. First we type the command:

   octave:96> subplot(1,1,1)
   

   which will open the main plotting window and allow you to make subplots.

2. Now, to plot the graph of f₁ with line width 5, we use:

   octave:97>plot(x,f_1, "linewidth", 5)
   

3. Set the axis limits to ensure space for the inset:

   octave:98> set(gca, "xlim", [-6 2.5], "ylim", [-50 70])
   

4. When we insert the smaller inset window, we specify the location of the lower-left corner of the inset and the length and height. We do so in fractions of the main plotting window (including the axis ticks). For example:

   octave:99> axes("position",[0.3 0.2 0.3 0.3])
   

5. To plot in the inset, we simply use the basic plot function:

   octave:100> plot(x, f_2, "red", "linewidth", 5)
