Question

我正在使用KendoUI条形图。请检查fiddle。在这个小提琴中，我在设计时设置series配置。我想在运行时点击按钮将series添加到图表中。如何在点击按钮时将series添加到剑道图表中。

当前series是在设计时分配的，我希望在运行时点击按钮时也这样做。

代码：

Answer 1

Ageonix给出了一个很好的答案！如果您不想对图表选项使用全局变量，可以从DOM数据属性获取图表实例，将系列添加到图表实例，然后告诉图表重绘：

var newseries = {
      name: "100+",
      stack: "Female",
      data: [654622, 625844, 784930, 844982, 900941, 39797, 72929, 118435, 118454]
};
//Get the chart
var chart = $("#chart").data("kendoChart");
//add the series
chart.options.series.push(newseries);
//refresh the chart
chart.redraw();

更新了 DOJO

Answer 2

如果将图表选项设置为全局变量，则可以修改options.series并在按钮单击事件中将其设置为更新的系列数据源，并再次调用createChart（），这将更新（重新创建）图表随着更新的系列。

创建全局chartOptions变量：

var chartOptions = 
{
  title: {
  text: "World population by age group and sex"
},
legend: {
etc. etc.

然后使用存储在变量中的选项创建图表：

$("#chart").kendoChart(chartOptions);

最后，使用更新的数据更新options.series并重新创建图表：

click: function() 
{
  chartOptions.series = updatedSeries;
  $("#chart").kendoChart(chartOptions);
}

我更新了你的Dojo并添加了一个按钮，用于在点击时填充新系列。 http://dojo.telerik.com/oTeTi/3
