如何使用 Matplotlib 绘制两个元组列表 [英] How to plot two lists of tuples with Matplotlib

问题描述

我有两个列表，其中每个元素都是一个元组，应解释为

I have two lists where each element is a tuple that should be interpreted as

x = [(x1_begin, x1_end), (x2_begin, x2_end), ... , (xn_begin, xn_end)]
y = [(y1_begin, y1_end), (y2_begin, y2_end), ... , (yn_begin, yn_end)] 

在一个图中，我想绘制所有这些点并在(yi_begin，yi_end)与(xi_begin，xi_end)code>代表所有i.

In one figure, I would like to plot all these points and draw lines only between (yi_begin, yi_end) vs (xi_begin, xi_end) for all i.

以下代码设法绘制所有点.但我不确定如何在点之间正确绘制线条.非常感谢您的帮助.

The following code manages to plot all the points. But I'm not sure how to draw the lines properly between the points. Any help is much appreciated.

import matplotlib.pyplot as plt

x = [(1, 27), (32, 55), (56, 80), (84, 103)]
y = [(5, 7), (3, 6), (4, 9), (6, 11)]

fig = plt.figure()
ax = fig.add_subplot(111)
ax.scatter(x, y, color='black')
plt.show()

推荐答案

如果确实要为每个元组请求一行，则代码如下.

If indeed you are asking for one line per tuple, here's the code.

fig = plt.figure()
ax = fig.add_subplot(111)
assert len(x) == len(y)
for i in range(len(x)):
    plt.plot(x[i], y[i])
plt.show()

给你
