I'm trying to integrate a Multilevel Sankey Google Chart(https://developers.google.com/chart/interactive/docs/gallery/sankey) in a Cognos Analytics Custom Control and I'm having some troubles with JavaScript.

I have checked google code and it works fine in a HTML file:

<html> <body> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <div id="sankey_multiple" style="width: 900px; height: 300px;"></div> <script type="text/javascript"> google.charts.load("current", {packages:["sankey"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('string', 'From'); data.addColumn('string', 'To'); data.addColumn('number', 'Weight'); data.addRows([ [ 'Brazil', 'Portugal', 5 ], [ 'Brazil', 'France', 1 ], [ 'Brazil', 'Spain', 1 ], [ 'Brazil', 'England', 1 ], [ 'Canada', 'Portugal', 1 ], [ 'Canada', 'France', 5 ], [ 'Canada', 'England', 1 ], [ 'Mexico', 'Portugal', 1 ], [ 'Mexico', 'France', 1 ], [ 'Mexico', 'Spain', 5 ], [ 'Mexico', 'England', 1 ], [ 'USA', 'Portugal', 1 ], [ 'USA', 'France', 1 ], [ 'USA', 'Spain', 1 ], [ 'USA', 'England', 5 ], [ 'Portugal', 'Angola', 2 ], [ 'Portugal', 'Senegal', 1 ], [ 'Portugal', 'Morocco', 1 ], [ 'Portugal', 'South Africa', 3 ], [ 'France', 'Angola', 1 ], [ 'France', 'Senegal', 3 ], [ 'France', 'Mali', 3 ], [ 'France', 'Morocco', 3 ], [ 'France', 'South Africa', 1 ], [ 'Spain', 'Senegal', 1 ], [ 'Spain', 'Morocco', 3 ], [ 'Spain', 'South Africa', 1 ], [ 'England', 'Angola', 1 ], [ 'England', 'Senegal', 1 ], [ 'England', 'Morocco', 2 ], [ 'England', 'South Africa', 7 ], [ 'South Africa', 'China', 5 ], [ 'South Africa', 'India', 1 ], [ 'South Africa', 'Japan', 3 ], [ 'Angola', 'China', 5 ], [ 'Angola', 'India', 1 ], [ 'Angola', 'Japan', 3 ], [ 'Senegal', 'China', 5 ], [ 'Senegal', 'India', 1 ], [ 'Senegal', 'Japan', 3 ], [ 'Mali', 'China', 5 ], [ 'Mali', 'India', 1 ], [ 'Mali', 'Japan', 3 ], [ 'Morocco', 'China', 5 ], [ 'Morocco', 'India', 1 ], [ 'Morocco', 'Japan', 3 ] ]); // Set chart options var options = { width: 600, }; // Instantiate and draw our chart, passing in some options. var chart = new google.visualization.Sankey(document.getElementById('sankey_multiple')); chart.draw(data, options); } </script> </body> </html>

This is my code for the custom control:

define( ["https://www.gstatic.com/charts/loader.js"], function() { "use strict"; function Control(){ }; Control.prototype.initialize = function( oControlHost, fnDoneInitializing ){ console.log('entra en initialize'); this.m_oControlHost = oControlHost; fnDoneInitializing(); console.log('sale de initialize'); }; Control.prototype.destroy = function( oControlHost ) { this.m_oControlHost = null; }; Control.prototype.getConfigurationValue = function( sName, sDefaultValue ) { var o = this.m_oControlHost.configuration; return ( o && ( o[sName] !== undefined ) ) ? o[sName] : sDefaultValue; }; Control.prototype.drawChart = function () { console.log('entra en drawChart'); var data = new google.visualization.DataTable(); data.addColumn('string', 'From'); data.addColumn('string', 'To'); data.addColumn('number', 'Weight'); data.addRows([ [ 'Brazil', 'Portugal', 5 ], [ 'Brazil', 'France', 1 ], [ 'Brazil', 'Spain', 1 ], [ 'Brazil', 'England', 1 ], [ 'Canada', 'Portugal', 1 ], [ 'Canada', 'France', 5 ], [ 'Canada', 'England', 1 ], [ 'Mexico', 'Portugal', 1 ], [ 'Mexico', 'France', 1 ], [ 'Mexico', 'Spain', 5 ], [ 'Mexico', 'England', 1 ], [ 'USA', 'Portugal', 1 ], [ 'USA', 'France', 1 ], [ 'USA', 'Spain', 1 ], [ 'USA', 'England', 5 ], [ 'Portugal', 'Angola', 2 ], [ 'Portugal', 'Senegal', 1 ], [ 'Portugal', 'Morocco', 1 ], [ 'Portugal', 'South Africa', 3 ], [ 'France', 'Angola', 1 ], [ 'France', 'Senegal', 3 ], [ 'France', 'Mali', 3 ], [ 'France', 'Morocco', 3 ], [ 'France', 'South Africa', 1 ], [ 'Spain', 'Senegal', 1 ], [ 'Spain', 'Morocco', 3 ], [ 'Spain', 'South Africa', 1 ], [ 'England', 'Angola', 1 ], [ 'England', 'Senegal', 1 ], [ 'England', 'Morocco', 2 ], [ 'England', 'South Africa', 7 ], [ 'South Africa', 'China', 5 ], [ 'South Africa', 'India', 1 ], [ 'South Africa', 'Japan', 3 ], [ 'Angola', 'China', 5 ], [ 'Angola', 'India', 1 ], [ 'Angola', 'Japan', 3 ], [ 'Senegal', 'China', 5 ], [ 'Senegal', 'India', 1 ], [ 'Senegal', 'Japan', 3 ], [ 'Mali', 'China', 5 ], [ 'Mali', 'India', 1 ], [ 'Mali', 'Japan', 3 ], [ 'Morocco', 'China', 5 ], [ 'Morocco', 'India', 1 ], [ 'Morocco', 'Japan', 3 ] ]); // Set chart options var options = { width: 600 }; var chart = new google.visualization.Sankey(document.getElementById('sankey_multiple')); chart.draw(data, options); console.log('sale de drawChart'); }; Control.prototype.draw = function( oControlHost ){ console.log('entra en draw'); var elContainer = oControlHost.container; elContainer.innerHTML ='<div id="sankey_multiple" style="width: 900px; height: 300px;"></div>'; google.charts.load('visualization', '1.1', {'packages': ['sankey']}); google.charts.setOnLoadCallback( this.drawChart.bind(this)); console.log('sale de draw'); }; Control.prototype.setData = function( oControlHost, oDataStore ){ console.log('entra en setData'); this.m_oDataStore = oDataStore; console.log('sale de setData'); }; return Control; });

When I run the report nothing happens, but if I resize the browser window I have this error that I don't know how to solve it:

Error: Mismatched anonymous define() module: function (exports,d3Array,d3Collection,d3Shape) { 'use strict';...
