Question

Write a python program to create the line chart from the data given below:

Product Trends by Month
Product	Jan	Feb	Mar	Apr	May	Jun
Desktop	80	45	25	20	10	5
Laptop	30	25	35	50	45	55
Tablet	10	15	20	35	60	95

Answer 1

Here is a code in Python 3.0 which plots a graph of sales of three different items with respect to the month. The month are taken on X-axis as the sale of products on the Y-axis. All three products have been shown with three different colored lines.

CODE:

#importing the requied libraries
import numpy as np
import matplotlib.pyplot as plt
#defining the X-axis with months
x = ['Jan','Feb','Mar','Apr','May','Jun']
#data formation for desktops
jan = 80;feb = 45;mar = 25;apr = 20;may = 10;june = 5
desktop = [jan, feb, mar, apr, may, june]

#data formation for laptops
jan = 30;feb = 25;mar = 35;apr = 50;may = 45;june = 55
laptop = [jan, feb, mar, apr, may, june]

#data formationfor tablets
jan = 10;feb = 15;mar = 20;apr = 35;may =60;june = 95
tablet = [jan, feb, mar, apr, may, june]

#plotting desktop data with respective month sale
plt.plot(x,desktop,marker='o', color='skyblue', linewidth=4,label='Desktop')
#plotting laptop data with respective month sale
plt.plot(x,laptop,marker='^', color='olive', linewidth=2, label='Laptop')
#plotting tablet data with respective month sale
plt.plot(x,tablet,marker='*', color='red', linewidth=2, label='Tablet')

#setting the Y-axis range and intervals
plt.yticks(np.arange(0, 100, 5))

plt.xlabel('Month') #the label for X-axis
plt.ylabel('Sale')# the label for Y-axis
plt.title('Product Trends by Month')#the title of the plot

plt.legend();#the legend for the plot
plt.show()#show the plot
