    The matplotlib.pyplot.subplots() function can create multiple subplots in a single figure, and by using the subplot_kw parameter, you can specify a projection type for the axes — such as 'polar', '3d', or a Cartopy geographic projection.

    Example – Creating Polar and Cartesian Subplots Together:

    import matplotlib.pyplot as plt
    import numpy as np

    x = np.linspace(0, 2*np.pi, 400)
    y = np.sin(x**2)

    # Create a 1x2 grid: left is Cartesian, right is Polar
    fig, (ax1, ax2) = plt.subplots(
    1, 2,
    subplot_kw={ 'projection': None } # default for ax1
    )

    # Replace ax2 with polar projection
    ax2.remove()
    ax2 = fig.add_subplot(122, projection='polar')

    # Plot data
    ax1.plot(x, y)
    ax1.set_title("Cartesian Plot")

    ax2.plot(x, y)
    ax2.set_title("Polar Plot")

    plt.tight_layout()
    plt.show()

    • subplot_kw lets you set projection for all subplots at creation.

    • To mix projections in one figure, remove and recreate specific axes with fig.add_subplot(..., projection=...).

    What is a projection in Matplotlib?
    In Matplotlib, a projection defines how the data coordinates are mapped onto the canvas or figure. The default projection in Matplotlib is the rectangular projection, which maps the data coordinates directly onto the figure’s axes.

    • We can create a figure with either one or both of the axis shared across the subplots in matplotlib. We have to specify the sharex and sharey parameters to True in the matplotlib.pyplot.subplots()function. The y-axis cannot be shared vertically and the x-axis cannot be shared horizontally for the subplots. Sharing axes results in the common xticks ...
