Histograms in Matplotlib are a powerful way to visualize the distribution of numerical data. They group data into bins and display the frequency of values within each bin.
Basic Histogram
To create a simple histogram, you only need a 1D array of numbers. You can control the number of bins with the bins parameter.
import matplotlib.pyplot as pltimport numpy as np# Generate random datanp.random.seed(19680801)data = np.random.normal(200, 25, size=100)# Basic histogramplt.hist(data, bins=10)plt.xlabel('Value')plt.ylabel('Frequency')plt.title('Basic Histogram')plt.show()Copied!âś•CopyThis will display a histogram with 10 equally spaced bins.
Customizing the Histogram
You can adjust style, density, colors, and bin widths for better visualization.
# Custom histogram with style changesplt.hist(data, bins=20, density=True, histtype='stepfilled',facecolor='g', alpha=0.75)plt.xlabel('Value')plt.ylabel('Probability')plt.title('Styled Histogram')plt.show()Copied!âś•CopyHere:
