To make a frequency histogram from a list with tuple elements in Python, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Make a list of tuples, data.
- Make lists of frequency and indices, after iterating the data.
- Make a bar plot usig bar() method.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True data = [("a", 1), ("c", 3), ("d", 4), ("b", 2), ("e", 7), ("f", 3), ('g', 2)] ind = [] fre = [] for item in data: ind.append(item[0]) fre.append(item[1]) plt.bar(ind, fre) plt.show()
Output
It will produce the following output −
