Python | Winter Colormap for Plotting Figure

In this article, we are going to learn how to apply winter colormap in a python figure using matplotlib?
Submitted by Anuj Singh, on August 18, 2020

Winter colormap is used in contrast plotting and in the following example, we have illustrated the use of winter colormap in scatter and a simple heatmap plot. Matplotlib.pyplot has an inbuilt defined function for winter plotting i.e. matplotlib.pyplot.winter().

Python code for winter colormap for plotting figure

import numpy as np
import matplotlib.pyplot as plt

imm = np.array([[0.8, 2.4, 2.5, 3.9, 0.0, 4.0, 0.0],
                    [2.4, 0.0, 5.0, 5.0, 2.7, 5.0, 0.0],
                    [2.1, 2.4, 5.8, 4.3, 5.9, 4.4, 2.0],
                    [4.6, 0.0, 3.3, 5.0, 3.1, 0.0, 0.8],
                    [4.7, 0.7, 5.6, 2.6, 2.2, 6.2, 3.0],
                    [1.3, 5.2, 2.0, 5.5, 5.9, 3.2, 5.1],
                    [0.1, 2.0, 5.0, 1.4, 5.0, 1.9, 6.3]])

plt.figure()
plt.imshow(imm)
plt.winter()
plt.colorbar()
plt.title('Winter Colormap')
plt.show()

plt.figure()
plt.imshow(imm)
plt.winter()
plt.colorbar()
plt.axis(False)
plt.title('Winter Colormap')
plt.show()

##################################
x = np.arange(50)
y = np.random.randint(0,50,50)
ss = np.random.randint(0,50,50)
c = np.random.randint(0,50,50)

plt.figure()
plt.winter()
plt.scatter(x,y, s=ss*25, c=c, marker='o')
plt.title('Winter Colour Map in Scatter Plot Example')
plt.colorbar()

plt.figure()
plt.winter()
plt.scatter(x,y, s=ss*25, c=c, marker='o')
plt.title('Winter Colour Map in Scatter Plot Example')
plt.axis(False)
plt.colorbar()

Output:

Output is as Figure
