Plotting the Bar chart in Matlab

Hi all,

I am plotting the bar chart in matlab with the following code,

 x = [1 2 3];
 figure,
 bar(x,[3 2 1;6 5 4;9 8 7]) 

Here, I am getting the following chart when I run it, but it should be (3,6,9) should be below the 1(x-axis), (2,5,8) under the 2(x-axis), similarly (1,4,7) in 3(xaxis).

It would be great, if anyone could help.

Thanks,

Satish J

Hi,

The data in your matrix is being plotted in columns rather than rows. To achieve the desired grouping, you should transpose the matrix. You can do this by using the transpose operator ('). Here's the updated code:

x = [1 2 3];
y = [3 2 1; 6 5 4; 9 8 7]';
figure,
bar(x, y)
