Question

python 3.7 please help

what command do I use to make a scatterpot in python?

Answer 1

Solution : To implement a scatterplot in python , we can use the matplotlib library. Matplotlib has a built in function to create scatterplots called scatter(). A scatter plot shows the data as a collection of points. We use matplotlib.show() to see the output.

Code :

import matplotlib.pyplot as plt

a = [4,6,7,6,1,15,2,7,5,12,13,7,5] #data for x-axis
b = [95,81,82,83,106,81,104,82,89,73,72,80,81] #data for y-axis

plt.scatter(a, b)
plt.show()

Output :

For random data distributions :

We use numpy.random.normal() function which is of the format :

numpy.random.normal(mean,standard deviation, random numbers)

Code :

import numpy as np
import matplotlib.pyplot as plt

a = np.random.normal(8.0, 3.0, 500) #random data
b = np.random.normal(10.0, 6.0, 500) #random data

plt.scatter(a, b)
plt.show()

Output :
