How To Use It?

The usage of this little function is easy. After having created a plot as usual, e.g.

% clear the workspace

% generate a random matrix
mat_data = rand(30, 3);

% plot the data
figure(1);
plot(mat_data);
xlabel('day of month');

... and adding a legend

% create a standard legend
% (and obtain the handle)
legend({'number of shoes', ...
        'enemies confused', ...
        'raindrops falling on my head'});

the legend entries can be transformed into toggle switches as easy as this:

% now change the legend to be clickable
legend_curve_selector(legend);
