pyecharts为什么画不出来图

数据

代码：

import pandas as pd
import pyecharts.options as opts
from pyecharts.charts import Bar
from pyecharts.globals import ThemeType
data=pd.read_csv('presidential_approval_rate.csv')
y4=data['political_issue'].size
datax=['支持','反对','不发表意见']
for i in range(y4):
    issue=data.loc[i,'political_issue']
    y1=data.loc[i,['support','oppose','no_opinion']]
    y1=list(y1)
    print(issue)
    print(y1)
    bar=(Bar(init_opts=opts.InitOpts(theme=ThemeType.LIGHT))
         .add_xaxis(datax)
         .add_yaxis(issue,y1,stack=True)
         .set_series_opts(      #set_series_opts系列配置设置
                      label_opts=opts.LabelOpts(position="inside",
                      color="black", font_size=13,font_style="italic",
                      font_weight='normal',font_family='SimSun',
                      formatter="{c}"))
        .set_global_opts(title_opts=opts.TitleOpts(title="柱状图数据堆叠"))
         )
    bar.render("比例中的柱状数据堆叠图2.html")

运行结果：输出的issue、y1和图
