Intro to Matplotlib in Python, Part1-plot().

1. What is Matplotlib
It is a library which helps us to plot and visualize the data in 2D form. It is an easy way to represent huge amount of data. It was introduced by John D.Hunter in the year 2002.

2. Why Matplotlib

• Easy visualization to data.

• Consist of bar graphs, histograms, pie charts, line graphs, etc.

• Compatible with other third-party libraries and packages, that extend its functionality.

3. Plotting on X and Y axis

• By default, the plot() function draws a line from point to point.
• Also draws points on graph.
• positions of points are in order. Eg(10,7), here 10 is point on X axis and 7 on Y axis.
• Example:

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 8])
y = np.array([3, 10])
plt.plot(x,y)
plt.show()

OUTPUT

NOTE

• The x-axis is the horizontal axis.

• The y-axis is the vertical axis.
