Introduction
This tutorial will guide you through creating a simple plot using Python's Matplotlib library. Matplotlib is a data visualization library widely used in scientific computing to create static, animated, and interactive visualizations in Python.
VM Tips
After the VM startup is done, click the top left corner to switch to the Notebook tab to access Jupyter Notebook for practice.
Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook.
If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
Import necessary libraries
Before we start creating the plot, we need to import the necessary libraries. In this case, we need to import numpy and matplotlib.pyplot.
import numpy as np
import matplotlib.pyplot as plt
Generate Data
We need to generate data for the plot. In this example, we will generate two arrays, t and s.
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)
Create the plot
Now that we have the data, we can create the plot. First, we create a figure and axis object using plt.subplots(). Then, we plot the data using ax.plot().
fig, ax = plt.subplots()
ax.plot(t, s)
Add labels and title
We can add labels to the x and y axis, as well as a title to the plot using ax.set().
ax.set(xlabel='time (s)', ylabel='voltage (mV)', title='About as simple as it gets, folks')
Add a grid
Finally, we can add a grid to the plot using ax.grid().
ax.grid()
Show the plot
We can use plt.show() to display the plot.
plt.show()
Summary
This tutorial has walked you through creating a simple plot using Matplotlib. We started by importing the necessary libraries, generated data for the plot, created the plot, added labels and a title, and added a grid. Matplotlib is a powerful library for creating visualizations in Python, and this tutorial is just the beginning of what you can do with it.
