Scatter a 2D numpy array in matplotlib

MatplotlibPythonData Visualization

To scatter a 2D numpy array in matplotlib, we can take the following steps −


  • Set the figure size and adjust the padding between and around the subplots.

  • Create random data of 100×3 dimension.

  • Use the scatter() method to plot 2D numpy array, i.e., data.

  • To display the figure, use show() method.


import numpy as np
from matplotlib import pyplot as plt

# Set the figure size
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

# Random data of 100×3 dimension
data = np.array(np.random.random((100, 3)))

# Scatter plot
plt.scatter(data[:, 0], data[:, 1], c=data[:, 2], cmap='hot')

# Display the plot


It will produce the following output −
