Generated plots can be customized using the [MATLAB] or [Octave] GUI, or
programmatically. The following commands change some of the default properties
of the previous plot:

```matlab
% Get the current axes children objects
ch = get(gca, 'Children')
ch = get(gca, 'Children');
% Set the color of the '1e5' bars to white
set(ch(8), 'FaceColor', 'w')
set(ch(8), 'FaceColor', 'w');
% This is required in Octave for updating the legend
legend(gca);
% Change the default labels
ylabel('Average speedup over Selection sort')
ylabel('Average speedup over Selection sort');
xlabel('Algorithms');
```
