    %% Modify Appearance of Histogram Chart
% Create a histogram chart in polar coordinates, and then change its
% appearance. Specify the bar colors by setting the |FaceColor| property to
% a character vector of a color name, such as |'red'|, or an RGB triplet.
% Specify the transparency by setting the |FaceAlpha| property to a value
% between 0 and 1.

theta = atan2(rand(100000,1)-0.5,2*(rand(100000,1)-0.5));
polarhistogram(theta,25,'FaceColor','red','FaceAlpha',.3);
