Draw a curve connecting two points instead of a straight line in matplotlib
To draw a curve connecting two points instead of a straight line in matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Define a draw_curve() method to make a curve with a mathematical expression.
- Plot point1 and point2 data points.
- Plot x and y data points returned from the draw_curve() method.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True def draw_curve(p1, p2): a = (p2[1] - p1[1]) / (np.cosh(p2[0]) - np.cosh(p1[0])) b = p1[1] - a * np.cosh(p1[0]) x = np.linspace(p1[0], p2[0], 100) y = a * np.cosh(x) + b return x, y p1 = [0, 1] p2 = [1, 2] x, y = draw_curve(p1, p2) plt.plot(p1[0], p1[1], 'o') plt.plot(p2[0], p2[1], 'o') plt.plot(x, y) plt.show()
