how to make a bar chart with 2 bars in each category in matlab

You can create a bar chart with 2 bars in each category in MATLAB using the bar function. Here's an example code to demonstrate this:

main.m
% Define the data
categories = {'Category A', 'Category B', 'Category C'};
data1 = [10, 15, 20];
data2 = [8, 12, 18];

% Create a bar chart with 2 bars in each category
bar([data1; data2])

% Customize the chart
set(gca, 'XTickLabel', categories) % Set X-axis labels
legend('Bar 1', 'Bar 2') % Add a legend
xlabel('Categories') % X-axis label
ylabel('Values') % Y-axis label
title('Bar Chart with 2 Bars in Each Category') % Title of the chart

15 lines

In this code snippet, we first define the categories and the corresponding data for the two bars in each category. Then, we use the bar function to create a bar chart with two bars in each category. Finally, we customize the chart by setting labels, legends, and titles.

Make sure to replace the categories, data1, and data2 with your own data values.
