#8 - Write a program to plot a bar chart from the medals won by the four countries. Make sure that bars are separately visible.                                  

Country	Gold	Silver	Bronze	Total
India	26	20	20	66
Australia	80	59	59	198
England	45	45	46	136
Canada	10	12	14	36

  

import matplotlib.pyplot as plt

info=['Gold','Silver','Bronze','Total']

India=[26,20,20,66]

Australia=[80,59,59,198]

England=[45,45,46,136]

Canada=[10,12,14,36]

#7 - Given a series nfib that contains reversed Fibonacci numbers with Fibonacci numbers as show below:

[0, -1, -1, -2, -3, -5, -8, -13, -21, -34, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

 Write a program to plot nfib with following specifications:                

 (a)    The line color should be magenta

 (b)   The marker edge color should be black with size 5

 (c)    Grid should be displayed

import matplotlib.pyplot as plt

import numpy as np

nfib=[0,-1,-1,-2,-3,-5,-8,-13,-21,-34,0,1,1,2,3,5,8,13,21,34]

#6 - First 10 terms of Fibonacci series are stored in a list namely fib:          

 

fib = [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

 

Write a program to plot Fibonacci terms and their square-roots with two separate lines on the same plot.

(a)    Series should be plotted as a cyan line with ‘o’ markers having size as 5 and edge-color as red.

(b)   The square-root series should be plotted as a black line with ‘+’ markers having size as 7 and edge-color as red.
