To plot a time series in Python using matplotlib, we can take the following steps −Create x and y points using numpy.Plot the created x and y points using plot() method.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt import datetime import numpy as np plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.array([datetime.datetime(2021, 1, 1, i, 0) for i in range(24)]) y = np.random.randint(100, size=x.shape) plt.plot(x, y) plt.show()Output

To give sns.clustermap a dataset, we can take the following steps −Set multiple theme parameters in one step.Load an example dataset from the online repository (requires Internet).Return item and drop from the frame. Raise KeyError if not found, using pop() method.Plot a matrix dataset as a hierarchically-clustered heatmap using clustermap() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt import seaborn as sns plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True sns.set_theme(color_codes=True) iris = sns.load_dataset("iris") species = iris.pop("species") g = sns.clustermap(iris) plt.show()OutputRead More

To sharex when using subplot2grid, we can take the following steps −Create random data, t, x, y1 and y2 using numpy.Create a new figure or activate an existing figure using figure() method.Create a subplot at a specific location inside a regular grid with colspan=3 and rowspan=2.Create a subplot at a specific location inside a regular grid with colspan=3 and sharex=ax1 (step 3).Plot curve using t and y1 and y2 using plot() method.Adjust the padding between and around the subplots.To display the figure, use show() method.Exampleimport numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True t = np.arange(0.0, ...

To plot 3D graphs using Python, we can take the following steps −Create a new figure or activate an existing figure using figure() method.Get the 3D axes object.Make x, y, and z lists for data points.Add 3D scatter points using scatter3D() method, with x, y, and z data points with markersize=150 and marker=diamond.To display the figure, use show() method.Examplefrom mpl_toolkits.mplot3d import Axes3D from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = Axes3D(fig) x = [2, 4, 6, 3, 1] y = [1, 6, 8, 1, 3] z = [3, 4, 10, 3, 1] ax.scatter3D(x, y, ...

To add a text into a rectangle in matplotlib, we can add a label in annotate method at the center point of the rectangle.StepsCreate a figure or activate an existing figure using figure() method.Add a subplot arrangement in the current axis.To add a rectangle in the plot, use Rectangle() class to get the rectangle object.Add a rectangle patch on the plot.To add text label in the rectangle, we can get the center value of the rectangle, i.e., cx and cy.Use annotate() method to place text on the rectangle.Limit x and y axes to get a visible rectangle.To display the figure, use show() method.Examplefrom matplotlib ...

To get the center of a set of points, we can add all the elements of the list and divide that sum with the length of the list so that result could be the center of the corresponding axes.StepsMake two lists of data points.Plot x and y data points using plot() method.Get the center tuple of the x and y data points.Place the center point on the plot.Annotate the center as label for center of the x and y data points.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = [5, ...

To set color to a rectangle in matplotlib, we can take the following steps −Create a figure or activate an existing figure using figure() method.Add an '~.axes.Axes' to the figure as part of a subplot arrangement using add_subplot() method.A rectangle is defined via an anchor point with width and heights.Add a rectangle patch to the plot.Set the x and y limit using xlim() and ylim() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt, patches plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111) rectangle = patches.Rectangle((0, 0), 3, 3, edgecolor='orange', facecolor="green", linewidth=7) ax.add_patch(rectangle) plt.xlim([-5, 5]) plt.ylim([-5, 5]) ...

To scale axes in mplot3d, we can take the following steps −Create a figure or activate an existing figure using figure() method.Instantaite 3D axes instance using Axes3D() class.To scale X-axis, use set_xlim3d() method.To scale Y-axis, use set_ylim3d() method.To scale Z-axis, use set_zlim3d() method.To display the plot, use show() method.Examplefrom mpl_toolkits.mplot3d import Axes3D from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = Axes3D(fig) ax.set_xlim3d(-100, 100) ax.set_ylim3d(-100, 100) ax.set_zlim3d(-100, 100) plt.show()OutputRead More

To increase the font size of the legend in a Seaborn plot, we can use the fontsize variable and can use it in legend() method argument.StepsCreate a data frame using Pandas. The keys are number, count, and select.Plot a bar in Seaborn using barplot() method.Initialize a variable fontsize to increase the fontsize of the legend.Use legend() method to place legend on the figure with fontsize in the argument.To display the figure, use show() method.Exampleimport pandas import matplotlib.pylab as plt import seaborn as sns plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True df = pandas.DataFrame(dict(    number=[2, 5, 1, 6, 3],    count=[56, 21, 34, 36, ...

To adjust the size of a matplotlib legend box, we can use borderpad arguments in the legend method.StepsCreate line1 and line2 using two lists with different line widths.To place a legend on the figure and to adjust the size of legend box, use borderpad=2 in legend() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True line1, = plt.plot([1, 5, 1, 7], linewidth=0.7) line2, = plt.plot([5, 1, 7, 1], linewidth=2.0) plt.legend([line1, line2], ["line1", "line2"], bbox_to_anchor=(0.35, 1.0), borderpad=2) plt.show()Output
