  1. When plotting a histogram in Python using Matplotlib, you might encounter an issue where the histogram only plots one bin. This typically happens when the bins parameter is not set correctly.

    Example

    import matplotlib.pyplot as plt
    import numpy as np

    data = np.random.randn(1000)
    plt.hist(data, bins=1, color='skyblue', edgecolor='black')
    plt.xlabel('Values')
    plt.ylabel('Frequency')
    plt.title('Histogram with One Bin')
    plt.show()

    In the example above, setting bins=1 results in a histogram with only one bin.

    Solution: Adjusting the Bins Parameter

    To resolve this issue, you need to adjust the bins parameter to a more appropriate value. The bins parameter can be an integer specifying the number of bins or a sequence defining the bin edges.

    Example with Multiple Bins

    import matplotlib.pyplot as plt
    import numpy as np

    data = np.random.randn(1000)
    plt.hist(data, bins=30, color='skyblue', edgecolor='black')
    plt.xlabel('Values')
    plt.ylabel('Frequency')
    plt.title('Histogram with Multiple Bins')
    plt.show()
