Question

我使用该系列的json数据创建了一个高级图表。我需要刷新高清图并从其他json数据重绘新数据。我不知道怎么做t_T有人请帮助我..

这是我的代码

<?php
$con=mysqli_connect("localhost","root","","silo");

if (!$con) {
  die('Could not connect: ' . mysql_error());
}

您需要更新您的图表。

您可以执行简单的图表更新，更新图表信息（Chart Update API）
```
chart.update({
    title: {
       text: 'new text'
    }
})
```
JS fiddle更新图表正在运行中。

您可以执行更新图表数据本身的系列更新。（Series Update API）

// if data is in json format, convert it to an array
chart.series[0].update({
    data: [...]  //pass your new data here
});

系列更新

JS Fiddle。
