ApexCharts - 在运行时更新自定义变量、数组值
ApexCharts - Updating custom variable, array values on runtime
我想在运行时更新图表。
我的代码中有 2 个自定义变量数组（data_action 和 data_alt），我正在尝试更新它们。但是，它不起作用。所有预定义的变量，数组更新没有任何问题。
在下面的示例中，单击“更新图表”按钮时，图表数据和 x 轴标签会更新。但是，每个数据点的工具提示不会更新。
请指教
谢谢，
桑迪普

最初，我在“系列”中创建了“data_action”和“data_alt”作为单独的变量。因为，这些不是顶点库变量，“updateOptions”没有更新它们。所以，我不得不将它们添加到“数据”中。
