Basic Matplotlib Scatterplot


This post describes how to draw a basic scatterplot using matplotlib library. Once you understood the function, you can see the next post to customise your scatterplot chart.

This is a basic scatterplot example made with the plot() function of Matplotlib. These arguments are passed to the function:

  • x : x axis coordinates of the data points
  • y : y axis coordinates of the data points
  • data : an object with labelled data
  • linestyle : style of the lines between each point
  • marker : marker style of the points
# libraries
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
 
# Create a dataset:
df=pd.DataFrame({'x_values': range(1,101), 'y_values': np.random.randn(100)*15+range(1,101) })
 
# plot
plt.plot( 'x_values', 'y_values', data=df, linestyle='none', marker='o')
plt.show()
