To show mean in a box plot, we can use showmeans=True in the argument of boxplot() method.StepsSet the figure size and adjust the padding between and around the subplots.Create a random dataset.Create a new figure or activate an existing figure using figure() method.Add an axes to the current figure as a subplot arrangement.Make a box and whisker plot using boxplot() method.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.rand(100, 5) fig = plt.figure() ax = fig.add_subplot(111) bp = ax.boxplot(data, 'd', showmeans=True) plt.show()OutputRead More

To shade points in a scatter based on colormap, we can use copper colormap in scatter() method.StepsSet the figure size and adjust the padding between and around the subplots.Create x and y random 100 data points using numpy.Plot scatter points x and y with color=x and colormap=copper.To display the figure, use show() method.Exampleimport numpy as np from matplotlib import pyplot as plt, cm plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.random.rand(100) y = np.random.rand(100) plt.scatter(x, y, c=x, cmap='copper') plt.show()Output

To add textures to bars and wedges we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create a new figure or activate an existing figure using figure() method.Add an axes to the figure as part of a subplot arrangement.Make a list of hatches. Bars could be filled with some hatches.Create number bars as equivalent to number of hatches.Use bar() method to plot the bars with different hatch.To display the figure, use show() method.Exampleimport numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True ...
