我已经使用该系列的 json 数据制作了一个 highcharts。我需要刷新 highchart 并从其他 json 数据中重新绘制新数据。我不知道该怎么做，请有人帮助我..
这是我的代码
<?php

最佳答案
您需要更新您的图表。
您可以进行简单的图表更新，更新图表信息 ( Chart Update API )
chart.update({ title: { text: 'new text' } })JS fiddle正在运行的更新图表。
您可以进行系列更新，更新图表数据本身。 (Series Update API)
// if data is in json format, convert it to an array chart.series[0].update({ data: [...] //pass your new data here });JS Fiddle系列更新。
