我正在尝试将我的数据绘制成路径图。我试图为 4 辆汽车创建一条随机路径，而这 4 辆汽车想要拜访 5 位客户。

    #supplier_number = car _number
    customer_number=5
    supplier_number=4
    def new_xy_point():
        # data to be resides in 1st quadrant 0,90
        return uniform(0,90), uniform(0, 90)
def get_locations_as_xy(customer_number,supplier_number):
    array_xy = []
    for i in range(supplier_number):
        row =[]
        points = (new_xy_point() for x in range(customer_number)) 
        for point in points:
            row.append(point)
        array_xy.append(row)
    return array_xy

输出是：

在这里，我为每个客户设置了 x 轴和 y 轴。我需要根据这些值绘制图表。我需要输出类似i.stack.imgur.com/FH7bE.png 我对 python 和绘制 g 的经验不足，因此不胜感激。

您可以使用 matplotlib 轻松绘制数据。

首先将您的数据转换为 ax 和 y 列表。在这里，我将您的数据点列表称为 a。每辆车一条路径，由相应的数字标记。

import matplotlib.pyplot as plt

for idx, row in enumerate(a):
    x, y = [], []
    for x_, y_ in row:
        x.append(x_)
        y.append(y_)
     plt.plot(x, y, label=idx)

plt.legend()
plt.show()

在您提供的数据中，您有很多重复项，总共有 5 分。
