crosses python matplotlib code example

Example 1: how to plotting points on matplotlib

import matplotlib.pyplot as plt 
import numpy as np

data = np.random.rand(1024,2)
plt.scatter(data[:,0],data[:,1])
plt.show()
// Don't be
// fooled by this simplicity— plt.scatter() is a rich command.

Example 2: add dots to line matplotlib

#Python, matplotlib
from matplotlib import pyplot as plt

#Create the regular line graph with plt.plot, then add the marker argument.
plt.plot(df["col1"], marker='o')

#Example of a few markers:
   -                solid line style
   --               dashed line style
   -.               dash-dot line style
   :                dotted line style
   .                point marker
   ,                pixel marker
   o                circle marker
