How do you draw a line between two points in python?
To create line segments between two points in matplotlib, we can take the following steps Show
Exampleimport matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True point1 = [1, 2] point2 = [3, 4] x_values = [point1[0], point2[0]] y_values = [point1[1], point2[1]] plt.plot(x_values, y_values, 'bo', linestyle="--") plt.text(point1[0]-0.015, point1[1]+0.25, "Point1") plt.text(point2[0]-0.050, point2[1]-0.25, "Point2") plt.show() Output

I know there is another very similar question, but I could not extract the information I need from it. plotting lines in pairs I have 4 points in the
Now, I can plot the four points by doing:
But, apart from the four points, I would like to have 2 lines: 1) one connecting This is a simple toy example. In the real case I have 2N points in the plane. How can I get the desired output: for points with two connecting lines ? Thank you.

I think you're going to need separate lines for each segment:

Note, that function is a general function that can connect any two points in your list together. To expand this to 2N points, assuming you always connect point

It's almost always a good idea to avoid loops whenever possible, and matplotlib's In your case, you can do the following:
Have a long list of x's and y's, and want to connect adjacent pairs?
Want a specified (different) color for the dots and the lines?

JinjerJohnJinjerJohn 3432 silver badges5 bronze badges 1 Use the matplotlib.arrow() function and set the parameters head_length and head_width to zero to don't get an "arrow-end". The connections between the different points can be simply calculated using vector addition with: A = [1,2], B=[3,4] --> Connection between A and B is B-A = [2,2]. Drawing this vector starting at the tip of A ends at the tip of B.

JiadongJiadong 1,46413 silver badges32 bronze badges How do I make a line in Python?In Python, the new line character “\n” is used to create a new line. When inserted in a string all the characters after the character are added to a new line. Essentially the occurrence of the “\n” indicates that the line ends here and the remaining characters would be displayed in a new line.
How do you draw a horizontal line in Python?In matplotlib, if you want to draw a horizontal line with full width simply use the axhline() method. You can also use the hlines() method to draw a full-width horizontal line but in this method, you have to set xmin and xmax to full width.
