How to show mean in a box plot in Python Matploblib?
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()Output

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
Read MoreHow to use a custom png image marker in a plot (Matplotlib)?
To use custome png or jpg i.e an image as a marker in a plot, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Make a paths list to store the directories of images.Make a list (x and y) of points.Using subplots() method, create a figure and a set of subplots.To plot images instead of points, iterate zipped x, y and paths.Instantiate AnnotationBbox() with image and (x, y) points.Put xticks and yticks on both the axes.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt from matplotlib.offsetbox import OffsetImage, AnnotationBbox ...
Read MoreHow to plot a 3D continuous line in Matplotlib?
To plot a 3D continuous line 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 data points using numpy.Create z data points using x and y data points.Create a new figure or activate an existing figure using figure() method.Add an axes as a subplot arrangement with 3D projection.Plot x, y and z data points using plot() 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(-4 * np.pi, 4 ...
Read MoreChanging the color and marker of each point using Seaborn jointplot
To change the color and marker of each point using Seaborn jointplot, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Load an example dataset from the online repository (requires Internet).Use jointplot() method to plot tips data.Use cla() method to clear the current axes.Make a list of colors and markers for each point.Set the axes labels using set_axis_labels() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt import seaborn as sns import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True tips = sns.load_dataset("tips") g ...
Read MoreHow to put text at the corner of an equal aspect figure in Python/Matplotlib?
To put text at the corner of an equal aspect figure in matplotlib, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create a figure and a set of subplots, using subplots() method.Create x data points using numpy.Plot x on axis ax1, using plot() method.Plot x and 2*x on ax2, using plot() method.To put text in the corner of a figure use annotate() method for different axes.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 fig, axes = plt.subplots(2) x ...
Read MoreHow can I add textures to my bars and wedges in Matplotlib?
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 ...
Read MoreHow to plot cdf in Matplotlib in Python?
To plot cdf in matplotlib in Python, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Initialize a variable N for the number of sample data.Create random data using numpy.Compute the histogram of a set of data with data and bins=10.Find the probability distribution function (pdf).Using pdf (Step 5), calculate cdf.Plot the cdf using plot() method with label "CDF".Place a legend on the plot.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 N = 500 ...
