Matplotlib library is built upon Numpy. It is a Python library that is used to visualize data. It is a tree−like hierarchical structure which consists of objects that makeup each of these plots.

A ’Figure’ in Matplotlib can be understood as the outermost storage for a graph. This ‘Figure’ can contains multiple ‘Axes’ objects. ‘Axes’ object is NOT the plural form of ‘Axis’ in this case.

‘Axes’ can be understood as a part of ‘Figure’, a subplot. It can be used to manipulate every part of the graph inside it. A ‘Figure’ object in Matplotlib is a box that stores one or more ‘Axes’ objects. Under ‘Axes’ comes the tick marks, lines, legends, and text boxes in the hierarchy. Every object in the Matplotlib can be manipulated.

Time series, as the name suggests, is data that contains certain time periods or time stamps. It contains observations over certain time period. This kind of data tells us about how variables change over time based on various factors. Time series analysing and forecasting can be used to predict data with respect to some future time.

Following is an example −

import pandas as pd import matplotlib.pyplot as plt from datetime import datetime my_date = ['01−01−2018', '01−02−2018', '01−03−2018','01−04−2018', '01−05−2018', '01−06−2018', '01−07−2018', '01−08−2018'] my_price= [1,2,3,4,5,6,7,8] my_df = pd.DataFrame(my_date, my_price) my_df['value'] = [67, 99, 88, 34, 101, 21, 56, 77] my_df.columns = ['my_date', 'my_vals'] my_df['my_date'] = pd.to_datetime(my_df['my_date']) my_df.index = my_df['my_date'] del my_df['my_date'] my_df.plot(figsize=(15, 6)) plt.show()

The required packages are imported.

Data is generated and stored in a dataframe.

The ‘dates’ are converted to ‘datetime’ type.

The date column is stored as the index of the dataframe.

The plot is displayed on the console.
