To combine two heatmaps in seaborn, we can take the following steps −StepsSet the figure size and adjust the padding between and around the subplots.Create two Pandas data frames.Create a figure and a set of subplots, ax1 and ax2.Plot the rectangular data as a color-encoded matrix, on ax1 and ax2.Move ticks and ticklabels (if present) to the right of the axes.Keep the width of the padding between subplots minimum, as a fraction of the average axes width.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt import numpy as np import pandas as pd import seaborn as sns plt.rcParams["figure.figsize"] ...

To create a boxplot stratified by column in Python class, we can take the following steps −StepsSet the figure size and adjust the padding between and around the subplots.Create a Pandas data frame of two-dimensional, size-mutable, potentially heterogeneous tabular data.Compute the histogram of a set of data.Create a boxplot startified by column.To display the figure, use show() method.Exampleimport pandas as pd import numpy as np from matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True # Pandas dataframe df = pd.DataFrame({"column1": [4, 6, 7, 1, 8], "column2": [1, 5, 7, ...

To plot aggregated by date pandas dataframe, we can take the following steps −StepsSet the figure size and adjust the padding between and around the subplots.Create a data frame, df, of two-dimensional, size-mutable, potentially heterogeneous tabular data.Get the values of aggregated by date pandas dataframe.Plot the df (Step 3) with kind="bar".To display the figure, use show() method.Exampleimport numpy as np import pandas as pd from matplotlib import pyplot as plt, dates # Set the figure size plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True # Create a dataframe df = pd.DataFrame(dict(data=list(pd.date_range("2021-01-01", periods=10)), value=np.linspace(1, 10, 10))) df = df.groupby('data').agg(['sum']).reset_index() ...

To plot multiple boxplots in one graph in Pandas or Matplotlib, we can take the following steps −StepsSet the figure size and adjust the padding between and around the subplots.Make a Pandas data frame with two columns.Plot the data frame using plot() method, with kind='boxplot'.To display the figure, use show() method.Exampleimport pandas as pd import numpy as np from matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True # Pandas dataframe data = pd.DataFrame({"Box1": np.random.rand(10), "Box2": np.random.rand(10)}) # Plot the dataframe ax = data[['Box1', 'Box2']].plot(kind='box', title='boxplot') # Display ...
