我想在运行时更新图形。我有2个自定义变量数组在我的代码(data_action和data_alt)，我试图更新。但是，这行不通。所有预定义的变量，数组更新没有任何问题。
在下面的例子中，点击"更新图表"按钮、图形数据和x轴标签被更新。但是，每个数据点上的工具提示没有更新。请建议。
谢谢,Sandeep

最初，我创建了"data_action"one_answers";data_alt"作为"系列"中的独立变量。因为，这些不是顶级库变量，&;updateoptions &;没有更新。因此，我必须将它们添加到&;data&;中。
请参见下面的解决方案。
function fnPrint(){
try{
var oIframe = document.getElementById('printContent');
var gr = document.getElementById('chart').innerHTML;
gr = gr.substring(0,gr.indexOf('<div class="apexcharts-legend"'));
var oDoc = (oIframe.contentWindow || oIframe.contentDocument);
if (oDoc.document) oDoc = oDoc.document;
oDoc.write("<html><head><title>Line Graph</title>");
oDoc.write("</head><body onload='this.focus(); this.print();'>");
oDoc.write("<center><br /><br />" + gr + "</center></body></html>");
oDoc.close();
}
catch(e){
self.print();
