To set xticks and yticks with imshow() plot, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Get the current axis.Create a random dataset.Display the data as an image, i.e., on a 2D regular raster.Set x and y ticks using set_xticks() and set_yticks() method.To display the figure, use show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True ax = plt.gca() data = np.random.rand(6, 6) ax.imshow(data) # Set xticks and yticks ax.set_xticks([1, 2, 3, 4, 5]) ax.set_yticks([1, 2, 3, 4, 5]) ...

To remove white border when using subplot and imshow(), we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create random data points using numpy.Get the size of the data.Set the figure sizes in inches.Get the axes instance that contains most of the figure element.Turn off the axes.Add axes to the figure.Display the data as an image, i.e., on a 2D regular raster.To display the figure, use show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.randint(0, 50, (50, 50)) sizes ...

To show tick labels on top of a matplotlib plot, we can use the set_tick_params() method with labeltop=True.StepsSet the figure size and adjust the padding between and around the subplots.Create a figure and a set of subplots.Show the tick labels at the top of the plot. Use set_tick_parama() with labeltop=True.Hide the tick labels of the bottom axis of plot. Use set_tick_parama() with labeltop=False.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Create subplots fig, ax = plt.subplots(1, 1) # Show the ...

To pass a matplotlib object through a function; as Axis, Axes or figure, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.In plot() method, plot x and y data points at axes ax.In profile() method, create a figure and a set of subplots. Iterate the axes and pass in plot() method to plot the figure.Call the profile() method with 3 rows and 4 columns.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 def plot(ax, ...

To label bubble charts/scatter plot with column from Pandas dataframe, we can take the following steps −Set 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.Create a scatter plot with df.Annotate each data point with a text.To display the figure, use show() method.Exampleimport pandas as pd from matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Create a dataframe df = pd.DataFrame( dict( x=[1, 3, 2, ...

To get coordinates from the contour in matplotlib, we can take the following steps −Set the figure size and adjust the padding between and around the subplots.Create lists of x, y and m with data points.Use plt.contour(x, y, m) to create a contour plot with x, y and m data points.Get the contour collections instance.Get the path of the collections, and print the vertices or coordinates of the contour.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = [1, 2, 3, 4] y = [1, 2, 3, 4] m ...

LaTeX ignores the spaces you type and uses spacing the way it's done in mathematics texts. You can use the following four commands in case you want a different spacing style\; – thick space\: – medium space\, – a thin space\! – a negative thin spaceTo remove random unwanted space in LaTeX-style maths in matplotlib plot, we can use "\!" which will reduce the extra spacing.Let's take an example and understand how it works. We will have two sub-plots and then we will add a complex mathematical equation (using LaTex) in a textbox in both the sub-plots. However, we will ... Read More
