我想将 JSON 中的新数据替换为图表并将它们显示在图表中，而无需重新加载整个画布。是否可以在 AmCharts 库中使用，如果是，我该怎么做？

I had a similar issue previously. You just need to add the data to a new array and update the graph. The key elements are:
我以前有过类似的问题。您只需要将数据添加到新数组并更新图形。关键要素是：
//New data array
var NewChartData = [];
//Adding new data to array
NewChartData.push(JSON.parse(D));
//Setting the new data to the graph
chart.dataProvider = NewChartData;
//Updating the graph to show the new data
chart.validateData();
For this example I just used data from a DIV element on the page but you can use the same method to get the data from another source.
对于本示例，我仅使用了页面上 DIV 元素中的数据，但您可以使用相同的方法从其他来源获取数据。
