24 Pandas怎样结合Pyecharts绘制交互性折线图

24 Pandas怎样结合Pyecharts绘制交互性折线图？

背景：

• Pandas是Python用于数据分析领域的超级牛的库
• Echarts是百度开源的非常好用强大的可视化图表库，Pyecharts是它的Python库版本

1、读取数据

import pandas as pd

xlsx_path = "./datas/stocks/baidu_stocks.xlsx"
df = pd.read_excel(xlsx_path, index_col="datetime", parse_dates=True)
df.head()

.dataframe tbody tr th:only-of-type { vertical-align: middle; } <pre><code>.dataframe tbody tr th { vertical-align: top; } .dataframe thead th { text-align: right; } </code></pre>

	code	open	close	high	low	vol	p_change
datetime
2019-12-03	BIDU	115.199997	114.800003	116.019997	113.300003	3493249	-2.25
2019-12-02	BIDU	118.389999	117.440002	119.764999	116.400002	2203313	-0.92
2019-11-29	BIDU	118.300003	118.529999	118.690002	117.599998	1917004	-0.82
2019-11-27	BIDU	119.180000	119.510002	119.839996	118.440002	2341070	0.77
2019-11-26	BIDU	120.010002	118.599998	120.440002	118.099998	3813176	-1.43

df.index



    DatetimeIndex(['2019-12-03', '2019-12-02', '2019-11-29', '2019-11-27',
                   '2019-11-26', '2019-11-25', '2019-11-22', '2019-11-21',
                   '2019-11-20', '2019-11-19',
                   ...
                   '2019-01-15', '2019-01-14', '2019-01-11', '2019-01-10',
                   '2019-01-09', '2019-01-08', '2019-01-07', '2019-01-04',
                   '2019-01-03', '2019-01-02'],
                  dtype='datetime64[ns]', name='datetime', length=227, freq=None)



df.sort_index(inplace=True)
df.head()

.dataframe tbody tr th:only-of-type { vertical-align: middle; } <pre><code>.dataframe tbody tr th { vertical-align: top; } .dataframe thead th { text-align: right; } </code></pre>

	code	open	close	high	low	vol	p_change

2019-01-02	BIDU	156.179993	162.250000	164.330002	155.490005	2996952	NaN
2019-01-03	BIDU	158.750000	154.710007	159.880005	153.779999	3879180	-4.65
2019-01-04	BIDU	157.600006	160.949997	162.429993	157.250000	3847497	4.03

2、使用Pyecharts绘制折线图

# 如果没有安装，使用pip install pyecharts安装
from pyecharts.charts import Line
from pyecharts import options as opts

# 折线图
line = Line()

# x轴
line.add_xaxis(df.index.to_list())

# 每个y轴
line.add_yaxis("开盘价", df["open"].round(2).to_list())
line.add_yaxis("收盘价", df["close"].round(2).to_list())

# 图表配置
line.set_global_opts(
    title_opts=opts.TitleOpts(title="百度股票2019年"),
    tooltip_opts=opts.TooltipOpts(trigger="axis", axis_pointer_type="cross")
)

    <pyecharts.charts.basic_charts.line.Line at 0x201bd51d088>


# 渲染数据
line.render_notebook()
