饼图不弹出 HighCharts

Question

我正在尝试制作一个饼图来显示 python 课程的评分。但是每次我尝试运行它时，饼图不会弹出，只会弹出标题。我正在使用 HighCharts 创建饼图，它也应该是交互式的。这就是我用来创建饼图的内容。我也没有收到任何错误消息。请帮助我。

下面是我的代码：

import justpy as jp
import justpy as jp
import pandas as pa
from datetime import datetime
from pytz import utc 

data = pa.read_csv("reviews.csv", parse_dates=['Timestamp'])
share = data.groupby(['Course Name'])['Rating'].count()

Answer 1

我遇到了同样的问题。

我通过删除（或注释掉）下面的 2 行代码修复了它，它们设置了“plotBackgroundColor”和“plotBorderWidth" 属性为空：

chart_def = """ 
 {
    chart: {
        //plotBackgroundColor: null,  --> remove or comment out this line
        //plotBorderWidth: null, --> remove or comment out this line
        plotShadow: false,
        type: 'pie'
    },
