legappend appends new entries to a legend

This is an HG2 specific fork of Chad Greene's legappend and requires MATLAB R2014b or newer.

legappend(newStrings) appends newStrings to the existing legend. newStrings can be a 1D character array or a 1D cell array of strings. Character arrays are treated as a single string.

% Sample data x = 1:10; y1 = x; y2 = x + 1; % Plot a thing! figure plot(x, 'ro'); legend('Circle', 'Location', 'NorthWest'); % Add a thing! hold on plot(x, y2, 'bs'); legappend('Square') 

% Sample data x = 1:10; y1 = x; y2 = x + 1; y3 = x + 2; % Plot a thing! figure plot(x, 'ro'); legend('Circle', 'Location', 'NorthWest'); % Add two things! hold on plot(x, y2, 'bs', x, y3, 'g+'); legappend({'Square', 'Plus'}) 

If there are multiple legend objects in the current figure window (e.g. subplots), legappend operates only on the first legend object returned.
