How to deal with NaN values while plotting a boxplot using Python Matplotlib?

To deal with NaN value while plotting a boxplot using Python, we can take the following steps −

Steps

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

• Initialize a variable N for data samples and for range.

• Next create the random spread, center's data, flier high and low, get the concatenated data, and the filtered data.

• Create a box plot using boxplot() method.

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

Example

import matplotlib.pyplot as plt import numpy as np # Set the figure size plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True # Data samples N = 10 # Random spread spread = np.random.rand(N) # Center's data center = np.ones(N) # Flier high and low fh = np.random.rand(N)+N fl = np.random.rand(N)-N # Concatenated data data = np.concatenate((spread, center, fh, fl), 0) data[5] = np.NaN # Filtered data filtered_data = data[~np.isnan(data)] # Plot the boxplot plt.boxplot(filtered_data) plt.show()

Output

It will produce the following output −
