Matplotlib BarCharts

In this Matplotlib article, we want to learn about Matplotlib BarCharts, so Barcharts are graphical representations of categorical data where the length or height of bars corresponds to the magnitude of the data they represent. They are very useful in illustrating comparisons between different categories or showing the distribution of a single categorical variable. Bar charts are particularly effective for visualizing discrete data, and this makes them important tools in data analysis and communication.

 

 

First of all we need to install Python Matplotlib and you can use pip for that.

 

 

Creating BarCharts with Matplotlib

Matplotlib simplifies the creation of bar charts through its intuitive interface. Let’s dive into a basic example:

In this example, we use the plt.bar() function to create the bar chart. We pass the categories list containing the category labels and the values list containing the corresponding values. plt.xlabel(), plt.ylabel(), and plt.title() functions add labels and a title to the chart for clarity.

Customizing BarCharts

Matplotlib offers different customization options, and you can create bar charts according to specific requirements and preferences. These are some common customization techniques:

 

  • Bar Color: You can specify custom colors for the bars using the color parameter:

 

 

  • Bar Width: Adjusting the width of the bars can alter the visual appearance of the chart:

 

 

Edge Color and Line Width: Adding edge colors and adjusting line widths can enhance the clarity of the bars:

 

 

Horizontal Bar Chart: If desired, you can create horizontal bar charts by using the plt.barh() function:
