I have an array of random integers for which I have calculated the mean
and std
, the standard deviation. Next I have an array of random numbers within the normal distribution of this (mean, std).
I want to plot now a scatter plot of the normal distribution array using matplotlib. Can you please help?
Code:
random_array_a = np.random.randint(2,15,size=75) #random array from [2,15)
mean = np.mean(random_array_a)
std = np.std(random_array_a)
sample_norm_distrib = np.random.normal(mean,std,75)
The scatter plot needs x and y axis...but what should it be?
The closest thing you can do to visualise your distribution of 1D output is doing scatter where your x & y are the same. this way you can see more accumulation of data in the high probability areas. For example:
import numpy as np
import matplotlib.pyplot as plt
mean = 0
std = 1
sample_norm_distrib = np.random.normal(mean,std,7500)
plt.figure()
plt.scatter(sample_norm_distrib,sample_norm_distrib)
