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 plus(+) shape marker which is used in marking plots. In matplotlib.pyplot command marker='4' for our desired marker style and the following figure illustrates the example of the same.

Python code for plus (+) scatter marker

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='P', cmap='summer')
plt.title('Plus 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='P')
plt.title('Plus Marker 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='P', cmap='GnBu')
plt.title('Plus Marker Scatter Plot Example')
plt.colorbar()
