MATLAB 2D barh()

2D barh() is a function in MATLAB that creates a horizontal bar chart. It is used to visualize data in a graphical format, specifically for comparing different categories of data. This function plots the data horizontally, with the length of the bar representing the value of the data.

Syntax

The basic syntax for the 2D barh() function is as follows:

barh(y)

where y is a vector of data values that are used to generate the horizontal bars.

Example

The following example demonstrates the use of the 2D barh() function:

% Create an example vector of data
data = [10 25 32 18 26];

% Generate a horizontal bar chart
barh(data)

% Add labels and title to the chart
xlabel('Data Values')
ylabel('Categories')
title('2D Bar Chart')

The output of this code snippet would generate a horizontal bar chart with the data values on the x-axis and the categories on the y-axis, with the length of the bars representing the values.

Customization

The 2D barh() function can be customized by adding additional parameters. Some of the commonly used parameters include:

• 'Color': Use this parameter to change the color of the bars.
• 'FaceColor': Use this parameter to change the color of the face of the bars.
• 'EdgeColor': Use this parameter to change the color of the edges of the bars.
• 'BarWidth': Use this parameter to change the width of the bars.
• 'LineWidth': Use this parameter to change the width of the edges of the bars.

Conclusion

In conclusion, the 2D barh() function in MATLAB is a useful tool for visualizing data in a graphical format. By generating horizontal bar charts, it is possible to compare different categories of data and identify trends and patterns. This function can also be customized to change the appearance of the chart, making it more appropriate for different types of data.
