import plotly.plotly as py
import plotly.graph_objs as go

path = \'/home/v-gazh/PycharmProjects/us_data/counts.csv\'

df = pd.read_csv(path)
df[\'PERMNO\'] = df[\'PERMNO\'].map(lambda x : \'P\'+str(x) )  # 该了下类型 此行有可无
df.set_index([\'PERMNO\'], inplace=True)

 
trace1 = go.Bar(
    x=df.index,
    y=df[\'tickerCount\'].squeeze(),
    name=\'一个P对应TICKER个数\'
)
trace2 = go.Bar(
    x=df.index,
    y=df[\'exchcdCount\'].squeeze(),
    name=\'一个P对应EXCHCD个数\'
)
 
data = [trace1, trace2]
layout = go.Layout(
    barmode=\'group\'#分组
)
 
fig = go.Figure(data=data, layout=layout)
py.iplot(fig, filename=\'grouped-bar\')
