How to plot an image with non-linear Y-axis with Matplotlib using imshow?
To plot an image with non-linear Y-axis with matplotlib using imshow() method, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Add a subplot to the current figure.
- Set nonlinear Y-axis ticks.
- Create random data points using numpy.
- Display data as an image, i.e., on a 2D regular raster, with data.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True ax = plt.subplot(111) ax.yaxis.set_ticks([0, 2, 4, 8]) data = np.random.randn(5, 5) plt.imshow(data, cmap='copper') plt.show()
