Question

Using python create a function the calculates and then plots a histogram. Please write this function yourself! The function should take a one dimensional array, a title for the histogram, a label for the x-axis, the number of boxes in the histogram, and upper & lower limits of the histogram. It should bin the data and make a plot of this reduced data using the matplotlib “plot” command to make a simple line plot of the results. The data should be saved into a png file with the name“title.png”. Please dont use import cv2, use the matplotlib “plot” .

Explanation / Answer

import numpy as np
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt

##The function

def plot_histogram(data_array, title, x_label, no_of_boxes, upper_limit, lower_limit):
  
#calculation of bins
binwidth = (upper_limit - lower_limit) / no_of_boxes
bins = np.arange(lower_limit, upper_limit + binwidth, binwidth)

  
plt.hist(data_array, bins)

plt.title(title)
plt.xlabel(x_label)

#displays the histogram
plt.show()
  
#saves the data to png image in the same folder as this program

plt.savefig(title+'.png')

  
return

##You can test the function with the statement

plot_histogram([1,2], "histogram_title", "x_label", 100, 100, -10)
