The line chart is one of the most common chart type. As a result, all the most common python data visualization libraries like
plotly allow to build it.
This page displays many line chart examples made with those tools. It goes from basic line chart tutorials to highly customized, polished examples 🔥.
⏱ Quick start
Making a simple line chart with
matplotlib is pretty straightforward thanks to the
If you provide only a series of values, it will consider that these values are ordered and will use values from 1 to n to create the X axis.🔥
For more control on the chart, see the dedicated section below.
import matplotlib.pyplot as plt
import numpy as np
# create data
# use the plot function
Line chart with
Matplotlib is a great fit to build line charts thanks to its
Line chart with several groups (
A line chart with multiple groups allows to show the evolution of several items on the same figure.
It is powerful but can quickly turn into a spaghetti chart: when too many lines are displayed they get cluttered and hard to read. Moreover, make sure to use inline labeling instead of a side legend that is very annoying to read.
The examples below explain how to build a line chart with multiple groups, and what are the alternatives to show your data a better way.
Line chart with Seaborn
Seaborn is another very good alternative when it comes to create line charts in Python. It comes with a powerful
lineplot() function that does most of the work for us.
Interactive line chart with plotly
If you are looking for an interactive version of a line chart with Python, plotly is definitely the library you need.
Its API is very straightforward to understand, and the output allows to zoom on the chart and have tooltip for markers:
Line chart with Pandas
Pandas offers a simple and efficient way to create line charts directly from DataFrames, eliminating the need for complex data manipulation.
Its integration with Matplotliballows for extensive customization, making it a versatile choice for quick data visualization tasks.
