I'm trying to create a bar chart for a matrix, its a 1x30 but I only want the 0, 10th, 20th and 30th values.

I've tried many formats such as in the image but I cannot manage to get it working.

Any suggestions out there?

I MATLAB, use the following syntax to index into an array.

bar([1 10 20 30], mean_1_1_walk([1 10 20 30]))

Also in MATLAB indexing start from 1, unlike some other programming languages (such as c/c++, java, python) where indexing starts from 0.

Would anyone know how to change the colours of these bars too?

bar([1 10 20 30], [mean_1_1_walk([1 10 20 30])' mean_1_2_walk([1 10 20 30])']);
