获取ETF历史行情数据，并用图形展示

通过akshare获取ETF历史行情数据
采用plotly展示图形

代码：

import akshare as ak
import plotly.express as px
import plotly.graph_objects as go

jsj_etf = ak.fund_etf_hist_sina(symbol="sz159998")

fig = px.line(jsj_etf, x="date", y="close", title='计算机ETF')

fig.add_trace(go.Scatter(x=[jsj_etf['date'].iloc[-1]],
                         y=[jsj_etf['close'].iloc[-1]],
                         text=[jsj_etf['date'].iloc[-1]],
                         mode='markers+text',
                         marker=dict(color='red', size=10),
                         textfont=dict(color='green', size=10),
                         textposition='top left',
                         showlegend=False))

fig.add_trace(go.Scatter(x=[jsj_etf['date'].iloc[-1]],
                         y=[jsj_etf['close'].iloc[-1]],
                         text=[jsj_etf['close'].iloc[-1]],
                         mode='markers+text',
                         marker=dict(color='red', size=10),
                         textfont=dict(color='green', size=10),
                         textposition='bottom center',
                         showlegend=False))

fig.show()

输出：
