How to get smooth interpolation when using pcolormesh (Matplotlib)?
To get smooth interpolation when using pcolormesh, we can use shading="gouraud" class by name.
Steps
Set the figure size and adjust the padding between and around the subplots.
Create data, x and y using numpy meshgrid.
Create a pseudocolor plot with a non-regular rectangular grid using pcolormesh() method.
To display the figure, use show() method.
Example
import matplotlib.pylab as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.random((3, 3)) x = np.arange(0, 3, 1) y = np.arange(0, 3, 1) x, y = np.meshgrid(x, y) plt.pcolormesh(x, y, data, cmap='RdBu', shading='gouraud') plt.show()
