To plot a time series array, with confidence intervals displayed in Python, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Get the time series array.Initialize a variable, n_steps, to get the mean and standard deviation.Get the under and above lines for confidence intervals.Plot the mean line using plot() method.Use fill_between() method to get the confidence interval.To display the figure, use show() method.Exampleimport numpy as np import pandas as pd import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True time_series_array = np.sin(np.linspace           ...

To write your own LaTeX preamble in Matplotlib, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create x and y random data points using numpy.Plot x and y data points using plot() method. Use LaTex formatting for the label.label="$y=e^{x}$"Place a legend on the figure using legend() method.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 x = np.linspace(-10, 10, 100) y = np.exp(x) plt.plot(x, y, color='red', label="$y=e^{x}$") plt.legend(loc='upper right') plt.show()OutputRead More

To plot y=1/x as a single graph in Python, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create data points using numpy.Plot x and 1/x data points using plot() method.Place a legend on the figure.To display the figure, use show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-10, 10, 101) plt.plot(x, 1/x, label='$f(x)=\frac{1}{x}$') plt.legend(loc='upper left') plt.show()Output

To change the separation between tick labels and axis labels in Matplotlib, we can use labelpad in xlabel() method.StepsSet the figure size and adjust the padding between and around the subplots.Plot data points of a list using plot() method.Set the ticks on the axes.Set X and Y axes margins to 0.Set the X-axis label with labelpad.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True plt.plot([1, 2, 3, 4, 5]) plt.xticks([1, 2, 3, 4, 5]) plt.margins(x=0, y=0) plt.xlabel("X-axis", labelpad=7) plt.show()Output

To modify the font size in Matplotlib-venn, we can use set_fontsize() method.StepsSet the figure size and adjust the padding between and around the subplots.Create three sets for Venn diagram.Plot a 3-set area-weighted Venn diagram.To set the set_labels and subset_labels fontsize, we can use set_fontsize() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt from matplotlib_venn import venn3 plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True set1 = {'a', 'b', 'c', 'd'} set2 = {'a', 'b', 'e'} set3 = {'a', 'd', 'f'} out = venn3([set1, set2, set3], ('Set1', 'Set2', 'Set3')) for text in out.set_labels:   ...
