高亮图上下文菜单按钮随页面刷新而增加

Question

我在一个网页上有超过1个高图。但是当我刷新页面时，我会在另外的高级图表中添加另一个上下文菜单按钮。我试图在重新创建之前破坏高图，但是没有用。任何想法如何阻止上下文菜单按钮增加页面刷新？

    // Submits form values and ...
$('#dateform').submit(function (event) {

    var data = $(this).serialize();

    var monthSelect = $("#month option:selected").text();
    var yearSelect = $("#year option:selected").text();
    $("#reportDate").text(monthSelect + " " + yearSelect);
