# Creating 2D Bar Charts Effectively In MatLab In data analyses, bar charts are very good respresentators of different datas. You can also create 2D bar charts in MatLab with ‘bar()’ command. In here, we explain how to create bar charts in MatLab with ‘bar()’ command below.

### How To Use ‘bar()’ Command In MatLab?

``````a = [2 6 3];
b = [1 3 5;4 4 6; 4 6 3];
x = bar(a,b)
``````

Here is a very basic example of use of ‘bar()’ command in Matlab Command Window. We created a vector ‘a’ and a matrix ‘b’. The dimension of matrix 3×3 and length of vector is 3. When you use ‘bar()’ command, write the vector and matrix inside it respectively as above. All the three elements in matrix’s rows will be placed in separate parts of bar graph. And these separated three bars will placed on numbers in vector ‘a’.

If you take a look at the result graph, you will understand the logic.

The output graph will be like above if you type these codes in MatLab. As you see, separate bar trios are placed upon 2nd, 3rd and 6th places according to elements of vector ‘a’.

``````a = [2 6 3];
x = bar(a)
``````

Also you can use ‘bar()’ command to create very simple bars that are created one vector or matrix as above. Look at the uotput bar graph below.

It is the simplest form of ‘bar()’ command in Matlab.

You can also edit these graphs; add titles, legends and annotations manually.
