Question

可以找到大量关于动态更改图表类型或数据输入的示例。如果您想为同一个图表应用两个输入但又希望彼此分开执行，那么遗憾的是没有示例。

在this示例中，有两个下拉列表，其中一个下拉列表可以选择图表类型，另一个下拉列表可以选择数据。我希望当您选择不同的图表类型时，图表会再次进行动画处理。选择新数据时也是如此。此外，当您首先必须启动时，标准变量现在已填充，以便您始终可以看到图形。

数据下拉列表有效。不幸的是，图表类型不起作用。这是唯一不起作用的东西。

JavaScript代码：

$(function() {

//create a variable so we can pass the value dynamically
var chartype = 'line';
var chartTitle = 'Browser Chart';
var chartCategories = ['Africa', 'America', 'Asia', 'Europe', 'Oceania'];
var chartData = [{

$("#chartType").change(function() {

      ['Others', 0.7]
    ]
  }];
  setDynamicChart(chartype, chartTitle, chartCategories, chartData);
  }
});

//function is created so we pass the value dynamically and be able to refresh the HighCharts on every click

function setDynamicChart(chartype, chartTitle, chartCategories, chartData) {
$('#grafiek_bench_rendement').highcharts({
  chart: {
    type: chartype
  },
  title: {
    text: chartTitle
  },
  xAxis: {
    categories: chartCategories
  },
  yAxis: {
    min: 0,
    title: {
      text: 'Total fruit consumption'
    }
  },
  plotOptions: {
    //this need only for pie chart
    pie: {
      allowPointSelect: true,
      cursor: 'pointer'
    }
  },
  series: chartData
});
}
});

我使用以下两个示例作为指南： Example 1 Example 2
