Construct a BarChartRace3D

Call the constructor to create a BarChartRace3D object

bcr3 = BarchartRace3D();

Optional configurations

These are optional configurations. If not set, the default will be used.

labels

Set the labels for the bars.

bcr3.labels = {'Bar1', 'Bar2', 'Bar3'};

2D/3D

Default to be 2D. Show 3D by setting this

bcr3.show3D=true;

output file name

Default to be BarChartRace3D.gif. Note only animation GIF out put is supported. Change to another filename by setting

bcr3.outfile = tmp.gif

title

Default to be empty.

bcr3.title = Title

color for each bar

It has builtin (default) colors. If you want to set the color, you can do this to set 3 colors (R, G, B) for example. If colors defined below is less than the bars, these colors will be reused. For this example, the forth bar will use R again.

bcr3.colors = [1 0 0; 0 1 0; 0 0 1];

positive only

BarChartRace3D handles positive and negative data by default for 2D mode. If you know all the data is positive, you can set the following, and then BarChartRace3D will use the whole canvas for showing positive data. Note 3D mode only handles positive data.

bcr3.positiveOnly=true;

set data and race

The data shall be an nxm array, where n is the number of iterations, and m is the number of bars.

data = randi(10, 8); bcr3.race(data);
