                 [1]:   import matplotlib.pyplot as plt
                        city=['Delhi', 'Mumbai','Chennai','Kolkata']
                        day1=[35,21,40,22]
                        day2=[30,25,36,20]
                        day3=[24,29,42,24]
                        plt.xlabel('Metro Cities' )
                        plt.ylabel('Temp in Celsius')
                        plt.title('Temperature Study of the Day')
                        plt.plot(city, day1)
                        plt.plot(city, day2)
                        plt.plot(city, day3)
                        plt.show()
              The above code will create a multiple line graph as shown below:






















              Plotting a bar chart

              It is used to plot data using rectangular bars or columns. It is generally used to compare values of two different
              categories. Example: marks of 5 subjects to compare, rise in population in five years, changing fuel price every
              month.

              Various versions of bar charts exist like single bar chart, double bar chart, etc can be used.
              Matplotlib uses a built-in function - bar () and plot() to create bar charts.
