Make filled polygons between two horizontal curves in Python using Matplotlib
Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack.
To create filled polygons between two curves a PolyCollection filling needs to be created between y1 and y2.
Parameters for the above task:
- x: It is an array of length N that holds data of x.
- y1: It is an array or a scalar of length N that holds data of y.
- y2: It is an array or a scalar of length N that holds data of y.
Below is the implementation.
import matplotlib.pyplot as plt x_inp = input ( "Enter values of X array: " ).split() x = [ int (i) for i in x_inp] y1_inp = input ( "Enter values of Y1 array: " ).split() y1 = [ int (i) for i in y1_inp] y2_inp = input ( "Enter values of Y2 array: " ).split() y2 = [ int (i) for i in y2_inp] color = input ( "Enter color: " ) plt.fill_between(x, y1, y2, color = color) plt.show() |
For input:
Enter values of X array: 1 2 3 Enter values of Y1 array: 1 2 1 Enter values of Y2 array: 1 4 1 Enter color: red
Output :
For input:
Enter values of X array: 1 2 3 4 5 Enter values of Y1 array: 1 2 3 2 1 Enter values of Y2 array: 3 5 7 5 3 Enter color: blue
Output :
