Drawing A Line Chart For A Pandas Series

Overview:

  • In a line chart, the data points are marked in a two-dimensional space at (x,y) positions and the points are connected through a line.
  • Line chart is one of the simplest data visualization techniques yet a powerful one that gives an idea about the trend of a variable against another variable.
  • For a pandas.Series instance, a line chart is drawn by calling the line() function on the plot member of the Series.
  • In the same way, to draw a line chart for a pandas DataFrame, the line() function can be called on the DataFrame.plot member.

Example:

# Python example program to create a line chart

import pandas as pds

import matplotlib.pyplot as plt

 

# GDP growth percentages

data    = [2.6, 2.3, 2.9, 3, 3.1];

 

# Create a pandas Series

series  = pds.Series(data, index=("Year1", "Year2", "Year3", "Year4","Year5"));

 

# Draw line chart

series.plot.line(title="GDP growth rate of a Country");

plt.show(block=True);
