%% Modify Baseline of Bar Graph
% This example shows how to modify properties of the baseline of a bar graph.

%%
% Create a bar graph of a four-column matrix. The |bar| function creates a
% bar series for each column of the matrix. Return the four bar series
% as |b|.

Y = [5, 4, 3, 5;
     3, 6, 3, 1;
     4, 3, 5, 4];
b = bar(Y);

%%
% All bar series in a graph share the same baseline. Change the value of
% the baseline to 2 by setting the |BaseValue| property for any of the bar
% series. Starting in R2014b, you can use dot notation to set properties.
% If you are using an earlier release, use the
% <docid:matlab_ref.f67-432995> function instead.

b(1).BaseValue = 2;

%%
% Change the baseline to a thick, red dotted line. 

b(1).BaseLine.LineStyle = ':';
b(1).BaseLine.Color = 'red';
b(1).BaseLine.LineWidth = 2;
