Hi, use the code below.

clc; close all;
% Define your 4-element matrix
y = [25 75 100 125];
% Plot bar graph
b = bar(y);
% Assign red colour to the second bar
b.FaceColor = 'flat';
b.CData(2,:) = [1 0 0];

Hope this helps!

it was showing an error as follows:

"No appropriate method, property, or field 'CData' for class

'matlab.graphics.chart.primitive.Bar'.

Did you mean:

>> b.XData (2, :) = [1 0 0];"

[Subhadeep Koley]

No I meant b.CData(2,:) = [1 0 0]; only.

Which matlab version are you using?

Also, can you show the matrix which you are trying to plot? (I mean you entire code)

It seems the built-in bar() function is being shadowed by a custom function with same name as "bar".
