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
