我正在尝试实现一个Highcharts图表，以便在.NET MVC中将新系列动态加载到同一图表中。我只需要根据一些属性将相同的数据集分组为几个组，并将这些组显示为多个系列。使用单选按钮选择要分组的属性。我已经使用Jquery编写了一个"on change"事件处理程序。为了加载多个系列，我删除了所有当前系列并添加了新系列。但他们返回了两个错误。
while (chart.series.length > 0) {
chart.series[0].remove(false);
}
chart.redraw();
此块将破坏现有系列。但它返回以下错误。

以下是加载新系列的代码。
if (i != (workCenterData.length - 1))
chart.addSeries({ data: dataArray }, false);
else
chart.addSeries({ data: dataArray }, true);
此块返回以下错误。

我尝试了这两种方法，在一个普通的HTML页面上点击一个按钮，销毁并重新生成新系列，它很有效。也许这与.NET有关。因为我参考了很多论坛，他们推荐了这些方法。很抱歉，我不能包括小提琴，因为我的数据取自数据库。有什么想法如何进行动态加载或消除这些错误吗？
没关系，我添加了一个假图例项作为图例标题出现，但我也编写了一个函数来销毁这个图例标题的符号。注释掉这个函数就成功了。它按照我现在想要的方式工作。
