如何用两个列表创建坐标 [x,y]（对于散点图 plot，matplotlib）

Question

Beginner here. In our g.netic course, we are asked to use Excel to create a plot, but I want to do it with Python. When I try to do a scatter plot, I get the line x=y . I think that I have to set my data as coordinate like

 data = [
    [1, 2],
    [3, 2],
    [4, 7],
    [2, 4],
    [...],
    ]

    x, y = zip(*data)
    plt.scatter(x, y)
    plt.show() 

as shown elsewhere. But I am struggling to do just that.

I did this for now, but I don't know how to use those two lists as [x, y] and then plot.

import pandas as pd
import matplotlib.pyplot as plt

def read_csvfile(file):
    df = pd.read_csv(file, sep=';', header=0)
    return df
   
cal = read_csvfile('Genotypage_BCM2531_snp49.csv')
x = cal['Signal_FAM']
y = cal['Signal_VIC']

plt.scatter(x, y)
plt.show() 

But I want to have clusters of coordinates [x,y], and it should look like this:

I think you want:

x,y = list(zip(*data))

plt.scatter(x,y)

Output:
