Drawing bar graph with different colors in Matlab 2013a

I am working with Matlab 2013a and I want to make a bar graph of a vector like v2=[2.4 9 18]

I want each bar will have different color

I have tried the following code, but it does not work:

v2 = [2.4 9 18];
handle = bar(v2);
barColorMap = jet(3);

for k = 1:3
    set(handle(k), 'FaceColor', barColorMap(k, :));
end

but it does not work. I appreciate if someone can help me on this.

Hi Shirin,

To define the color for a "Bar" individually, you can use the bar property "CData". You will first need to set the "FaceColor" property of the bar object to "flat" so that the chart uses the colors defined in the "CData" property.

The below code demonstrates how to achieve the same:

v2 = [2.4 9 18];
handle = bar(v2);
barColorMap = jet(3);

handle.FaceColor = 'flat';
handle.CData = barColorMap;

For more details, please refer to the following MathWorks documentation: https://www.mathworks.com/help/matlab/ref/bar.html#d126e83000:~:text=LineWidth%27%2C1.5)-,Control%20Individual%20Bar%20Colors,-Copy%20Code

Hope this helps!
