使用 Python 生成股票 K 线图

引言

        在股票分析中,经常需要用到 K 线图来分析股票的价格波动情况和交易量情况。本文将介绍如何使用 Python 和 pyecharts 库生成股票 K 线图,并将其保存为 HTML 文件。

准备数据

        首先,我们需要准备股票数据。在这里,我们使用 stock.csv 示例数据,该数据包括日期、开盘价、收盘价、最低价和最高价五个列。如果您没有相应的 CSV 文件,可以自行创建一个类似的文件。数据格式如下:

date,open,close,high,low
2022-01-03,40.0,41.0,41.5,39.5
2022-01-04,41.2,42.0,42.5,41.2
2022-01-05,42.5,42.6,42.9,42.0
2022-01-06,42.4,41.8,42.5,41.0
2022-01-07,42.0,42.9,43.0,41.8
2022-01-10,43.0,40.5,43.0,40.5
2022-01-11,40.5,39.5,41.0,39.5
2022-01-12,39.5,40.6,40.8,39.5
2022-01-13,40.6,41.2,41.5,40.0
2022-01-14,41.5,40.9,41.7,40.5

绘制 K 线图

        接下来,我们使用 pandas 库读取 stock.csv 数据,并保留需要用到的列并将其转换为列表。然后,我们将数据格式化为适合 K 线图的数据结构。最后,我们使用 pyecharts 库创建 K 线图对象,设置 x 轴和 y 轴等选项,添加数据并显示图表。

import pandas as pd
from pyecharts.charts
