Function “plot()”:

• “plot()” function creates a line graph.

• This function is accessible in the “matplotlib.pyplot” module.

• This “plot()” function creates a line graph by joining the data points with straight lines.

• The “plot()” function takes two lists as its input arguments.

• The first list represents the X coordinates of all the data points.

• The second list represents the Y coordinates of all the data points.

Syntax:

The “plot()” function has the following procedure in Python.

plt.plot(xcoordinates, ycoordinates)

Explanation:

Here,

• “plot()” is the function that creates a line graph.

• The variable “xcoordinates” is a list that contains the X coordinates of all data points.

• The variable “ycoordinates” is a list that has the Y coordinates of all data points.
