How to fill rainbow color under a curve in Python Matplotlib?
63 Lectures 6 hours
To fill rainbow color under a curve in Python Matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a user-defined method, plot_rainbow_under_curve(), that could have a list of 7 rainbow colors and create a set of data points "x" using numpy.
- Iterate in the range of 0 to 7 and plot the curve and fill the area between that curve.
- To display the figure, use show() method.
import numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True def plot_rainbow_under_curve(): rainbow_colors = ['violet', 'indigo', 'blue', 'green', 'yellow', 'orange', 'red'] x = np.linspace(-5, 5, 100) for i in range(0, 7): plt.plot(x, x ** 2, lw=0) plt.fill_between(x, x ** 2 + len(rainbow_colors)-i,color=rainbow_colors[i]) plot_rainbow_under_curve() plt.show()
