Getting Started with Matplotlib Pyplot Api

Step 1: Import Matplotlib

In this step, we are importing matplotlib that we will use in further steps.

import matplotlib.pyplot as plt

Step 2: Create Data

To visualize your desired data start by preparing it. This can include organizing a list of values, arrays or importing data from a source, like a CSV file.

Step 3: Create a Figure and Axes

Now, create a figure and axes; for your plot using the plt.subplots() function. This will provide you with the framework to create your representation.

fig, ax = plt.subplots()

Step 4: Plot Your Data

Create a representation of your data by choosing the plot type, such, as a line plot or scatter plot. Utilize the respective Pyplot function to generate your desired plot.

ax.plot(x_data, y_data, label='Data')

Step 5: Enhance Your Plot

In this step,.enhance your plot; labels, titles, legends and additional annotations to create an visually appealing visualization.

ax.set_xlabel('X-axis Label')
ax.set_ylabel('Y-axis Label')
ax.set_title('Title')
ax.legend()

Step 6: View or Store The Plot

Use plt.show() to display it in a window or utilize plt.savefig(‘plot.png’) to save it as an image.

plt.show()

Data visualization plays a key role in data science and analysis. It enables us to grasp datasets by representing them. Matplotlib, a known Python library offers a range of tools, for generating informative and visually appealing plots and charts. One outstanding feature of Matplotlib is its user-versatile interface called Pyplot API, which simplifies the process of creating plots. In this article, we will learn about Matplotlib Pyplot API in Python.

Prerequisite

• Python Matplotlib
• Pyplot
• Figure and Axes: In Matplotlib a figure serves as the container, for all components of a plot while axes represent the plotting area within a figure. It is possible to have subplots within a figure.
• Types of Plots: Matplotlib Pyplot offers support for plot types, such as line plots, scatter plots, bar plots, histograms and more. Each type of plot is suitable for kinds of data and analysis purposes.
