Cross(X) Scatter Marker in Matplotlib

There are few markers that can be used everywhere such as circular or square markers. But, matplotlib has some other inbuilt defined markers such as cross(X) shape marker which is used in marking plots.

Cross(X) Scatter Marker Illustrations

In matplotlib.pyplot command marker='4' for our desired marker style and the following figure illustrates the example of the same.

Python program for cross(x) scatter marker in matplotlib

import numpy as np
import matplotlib.pyplot as plt

# Example 1
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.scatter(x,y, s=ss*10, c=c, marker='X', cmap='summer')
plt.title('Cross Marker Scatter Plot Example')
plt.colorbar()

# Example 2
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.scatter(x,y, s=ss*10, c=c, marker='X')
plt.title('Cross Scatter Plot Example')
plt.colorbar()

# Example 3
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.scatter(x,y, s=ss*10, c=c, marker='X', cmap='GnBu')
plt.title('Cross Scatter Plot Example')
plt.colorbar()
