在不同宽度的可排序 div 中使用 amchart

Question

我有一个用 bootstrap 制作的页面，我在这个页面中有 2 个不同的部分，第一个使用 "col-lg-12"，第二个使用 "col-lg-6"，它们都是可拖动的。我想在其中放置一些 amcharts，一切正常，我的图表响应迅速，但是当我将大截面中的 div 移动到小截面图表时，图表响应功能停止工作并且不会自动调整大小。我的 html 代码

我不清楚到底是什么阻止了图表调整大小。

当您开始拖动大 div 时，图表父级的父级 div (.kt-portlet) 得到 display: none;。停止拖动后，它会设置回 flexbox 并且图表不再自动调整大小（尝试通过 devtools 手动更新 #kt_chart1 的宽度）。

但是，如果您手动将图表 div 的父级 (.kt-portlet__body) 或父级的父级的显示模式重置为 display: block;，然后不久之后将其删除，该图表可以再次 auto-resize。

因此，希望不会触发不希望的 incorrectly-styled 内容闪现的一种骇人听闻的方法是在 stop event of the slider 之后的短时间内执行上述操作：

            stop: function(event, ui) {
              setTimeout(function() {
                ui.item.css('display', 'block');
              }, 10);
              setTimeout(function() {
                ui.item.css('display', '');
              }, 20);
            },
