来自ajax调用函数的chart.data

Question

我想用 amCharts 制作一个图表，并有一些我通过 ajax 调用从服务器收到的值。 现在我想将这些数据用于我的图表 谁能告诉我该怎么做？

var chart = am4core.create("chartdiv", am4charts.XYChart);

  // Add data
  chart.data= (dont want to add data by myself)
  // Add and configure Series
  var pieSeries = chart.series.push(new am4charts.PieSeries());
  pieSeries.dataFields.value = "SalePrd";
  pieSeries.dataFields.category = "SaleYear";

和数据调用代码

var Ajax_URL= url;
  var Year_Val = GetSelectValue("YearSelect");
  var Prd_Val = GetSelectValue("PrdSelect");

  app.request.get(Ajax_URL, { "Token": Token_Data, "SaleYear":Year_Val, "SalePrd":Prd_Val }, function (data)
  {
    var data_Str=''+data;
    var data_Output = JSON.parse(data_Str);
    return data_Output;

  });
}

Answer 1

进行 ajax 调用，
然后在数据返回时绘制图表...

var Ajax_URL= url;
var Year_Val = GetSelectValue("YearSelect");
var Prd_Val = GetSelectValue("PrdSelect");

app.request.get(Ajax_URL, { "Token": Token_Data, "SaleYear":Year_Val, "SalePrd":Prd_Val }, function (data)
{
  var data_Str=''+data;
  var data_Output = JSON.parse(data_Str);
  
  var chart = am4core.create("chartdiv", am4charts.XYChart);

  // Add data
  chart.data = data_Output;

  // Add and configure Series
  var pieSeries = chart.series.push(new am4charts.PieSeries());
  pieSeries.dataFields.value = "SalePrd";
  pieSeries.dataFields.category = "SaleYear";
  
});
