Matplotlib 用线连接散点图点 - Python [英] Matplotlib connect scatterplot points with line - Python

问题描述

我有两个列表，日期和值.我想使用 matplotlib 绘制它们.下面创建了我的数据的散点图.

I have two lists, dates and values. I want to plot them using matplotlib. The following creates a scatter plot of my data.

import matplotlib.pyplot as plt

plt.scatter(dates,values)
plt.show()

plt.plot(dates, values) 创建一个折线图.

但我真正想要的是散点图，其中点由一条线连接.

But what I really want is a scatterplot where the points are connected by a line.

类似于在 R 中:

plot(dates, values)
lines(dates, value, type="l")

，这给了我一个点的散点图，上面覆盖着一条连接点的线.

, which gives me a scatterplot of points overlaid with a line connecting the points.

我如何在 python 中执行此操作?

How do I do this in python?

推荐答案

我认为@Evert 有正确的答案:

I think @Evert has the right answer:

plt.scatter(dates,values)
plt.plot(dates, values)
plt.show()

几乎一样

plt.plot(dates, values, '-o')
plt.show()

您可以将 -o 替换为另一个合适的格式字符串，如文档.您还可以使用 linestyle= 和 marker= 关键字参数拆分线条和标记样式的选择.

You can replace -o with another suitable format string as described in the documentation. You can also split the choices of line and marker styles using the linestyle= and marker= keyword arguments.
