How to plot a graph in python 📕📗

There are so many libraries available in python for graph plotting but this documentation contains the demostration of matplotlib.

Installation

pip install matplotlib
pip will take care of dependences itself so you don’t need to get worried about it.

Graph

You first need to import the package after installation by import matplotlib.pyplot as plt.
There is a inbuild funtion to plot the graph plot() which will take many arguments but I am passing two arguments x and y coordinates.

x = [x1, x2,x3]
y = [x4, x5, x6]
plt.plot(x, y)

Read more about plot function here @https://matplotlib.org/users/pyplot_tutorial.html
To display the graph you need to use show() function
plt.show()
It will plot a line graph with above coordinates
There are few more parameter in plot() funtion so let discuss about that
- xlabel :- For creating the label for x axis
- ylabel :- For creating the lablel for y axis

plt.xlabel('Countries')
plt.ylabel('Population in million')

Title function is used to give the title of the graph title()

plt.title('Pakistan India Population till 2010')

So By following the above steps you will end up with a simple line graph and you can read more about the graph plotting from the link below 😄 @ https://matplotlib.org/
