import dai

import bigcharts

start_date="2026-01-01"

end_date="2026-01-28"

sql = "select date, instrument,name,close from cn_stock_barld order by date, instrument"

df = dai.query(sql, filters={'date':[start_date,end_date], 'instrument':['300661，300769']}).df()

pivot_df = df.pivot(values='close',index='date',columns='name')

for ins in pivot_df.columns

pivot_df[ins]=round(pivot_df[ins]/pivot_df[ins].values[0],4)

line=bigchars.line(data=pivot_df,title=‘圣邦股份近期趋势’)

line.render()
