Simple (x,y) graph

[Sapphire_Ring]

Hi, I want to set up a simple graph with arbitrary x,y points, and then manually assign lines between those points. The problem with Matplotlib is that it tries to PLOT points. I want to just list a bunch of abitrary points with an x and a y value and manually draw lines between them. What program should I import to draw such a figure?

For drawing lines manually between the points, the gline function can be used. This tutorial explains the function and has some examples. https://www.mathworks.com/help/stats/gline.html

Thank you very much!

To achieve this, you can still rely on Matplotlib. You can apply the scatter function to display the arbitrary points and the plot function to manually connect them with lines. Here’s an example:

import matplotlib.pyplot as plt

# Define arbitrary points
points = [(1, 2), (3, 4), (5, 6), (7, 8)]

# Display points
x, y = zip(*points)
plt.scatter(x, y)

# Manually connect points with lines
plt.plot([1, 3], [2, 4])
plt.plot([5, 7], [6, 8])

plt.show()
