+% Creates a plot and provides a function to update the data in it.
+%   x     - Vector of x-values to plot for.
+%   y_lim - 1x2 vector containing the y limits of the plot.
+%   yfun  - Function or a cell array of functions of y data vectors
+%           that should be plotted. The output of each function
+%           will be plotted to the same axis.
+%
+%   update_data(t,varargin) - Function to update plot data. All varargin will
+%                             be passed to functions in yfun.
+%   plot_handles            - Array of plot_handles. One for each yfun.
+%   axis_handle             - Handle to the axis plotted to.
