how to show the distance between two curves in a graph

[termo]

I have these two curves. How could I plot a segment (and the number) whitch rapresent the distance between them (5 in this case) in the same graph?

1 2 3 4 5 6 7 8 9

import matplotlib.pyplot as plt   X_ev = [0, 1, 2, 3] Y1_ev = [10, 15, 20, 25] Y2_ev = [2, 10, 10, 15] plt.plot(X_ev,Y1_ev, 'g', label='Curve 1') plt.plot(X_ev,Y2_ev, 'r', label='Curve 2') plt.legend(numpoints=3) plt.show()

if looking for Euclidean distance between,

1 2 3 4 5 6 7

import numpy import matplotlib.pyplot as plt    X_ev = [0, 1, 2, 3] Y1_ev = [10, 15, 20, 25] Y2_ev = [2, 10, 10, 15] dist = numpy.linalg.norm(Y1_ev-Y2_ev)

untested, but I think this is correct

Sorry, I didn't explain myself well.
My aim is to draw the minimum distance between the points in the plot and not the curves.
I'd like to plot the line (length = SEGMENT) which links two points of different curves.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import matplotlib.pyplot as plt import numpy as np   X_ev = np.array([0, 1, 2, 3]) Y1_ev = np.array([10, 15, 20, 25]) Y2_ev = np.array([2, 10, 10, 15]) plt.plot(X_ev,Y1_ev, 'g', label='Curve 1') plt.plot(X_ev,Y2_ev, 'r', label='Curve 2')   SEGMENT = min(Y1_ev-Y2_ev) print('SEGMENT') print(SEGMENT)   plt.legend(numpoints=3) plt.show()

This?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

import matplotlib.pyplot as plt import numpy as np     def list_diff(l1, l2):     new_list = []     for n, item in enumerate(l1):         new_list.append(item - l2[n])     return new_list   X_ev = np.array([0, 1, 2, 3]) Y1_ev = np.array([10, 15, 20, 25]) Y2_ev = np.array([2, 10, 10, 15])   print(f"distance between points: {list_diff(Y1_ev, Y2_ev)}")   plt.plot(X_ev,Y1_ev, 'g', label='Curve 1') plt.plot(X_ev,Y2_ev, 'r', label='Curve 2')    SEGMENT = min(Y1_ev-Y2_ev) print('SEGMENT') print(SEGMENT)   plt.legend(numpoints=3) plt.show()

No, I'd like to have this (attachment)

Is this homework?

Do you mean a graph like this example: https://matplotlib.org/3.1.1/gallery/lin..._demo.html
