python - 循环行以在 Python 中的坐标对之间绘制线（matplotlib）

Question

我对 Python 有点陌生，我正在努力使用 matplotlib 制作以下情节：

使用以下数据：

我有很多行，所以我想做类似的事情：

For each row, plot a line from (x_start, y_start) to (x_end, y_end)

有什么建议吗？

谢谢！

You're on the right track. Import the data via something like pandas.read_csv(). Here, I just put everything into an array to make this simple.

In [1]: import numpy as np

In [2]: import matplotlib.pyplot as plt

In [3]: x = np.array([[1, 1, 3, 1], [2, 2, 4, 2], [3, 3, 5, 3], [4, 4, 6, 4], [5, 5, 7, 5]])

In [4]: plt.figure()
   ...: for row in x:
   ...:     plt.plot([row[0], row[2]], [row[1], row[3]], marker='.')
   ...:

In [5]: plt.show()

I leave the axis labels and the colors to you. Hint: look into matplotlib's colormaps.
