There are 3-4 charts in a Html page and i have a PDF download button on clicking the download button getting a pdf file in that we are unable to get the charts. we have used kendo drawing to download the Pdf

Below is the code that we have tried:

$scope.print = function(){
        kendo.drawing.drawDOM($("#page-Container")).then(function(group) {
            kendo.drawing.pdf.saveAs(group, "PdfDocumnet.pdf");
