Plotting data from a DataFrame
As with many mathematical problems, one of the first steps to finding some way to visualize the problem and all the information is to formulate a strategy. For data-based problems, this usually means producing a plot of the data and visually inspecting it for trends, patterns, and the underlying structure. Since this is such a common operation, pandas provides a quick and simple interface for plotting data in various forms, using Matplotlib under the hood by default, directly from a Series
or DataFrame
.
In this recipe, we will learn how to plot data directly from a DataFrame
or Series
to understand the underlying trends and structure.
Getting ready
For this recipe, we will need the pandas library imported as pd
, the NumPy library imported as np
, the Matplotlib pyplot
module imported as plt
, and a default random number generator instance created using the following commands:
from numpy.random import default_rng rng = default_rng(12345)
