Plotting at full resolution with matplotlib.pyplot, imshow() and savefig()

To plot at full resolution with matplotlib.pyplot, imshow() and savefig(), we can keep the dpi value from 600 to 1200.

Steps

• Set the figure size and adjust the padding between and around the subplots.
• Set random values in a given shape.
• Display the data as an image, i.e., on a 2D regular raster
• Save the figure with 1200 dpi.
• To display the figure, use show() method.

Example

from matplotlib import pyplot as plt
import numpy as np

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

data = np.random.rand(5, 5)

plt.imshow(data, cmap="plasma")
plt.savefig("myimage.eps", dpi=1200)

plt.show()

Output
