Hello, According to the ChartWrapper docs, the ChartWrapper handles loading all necessary libraries. If you have third party libraries then you must load them yourself explicitly.
- ChartWrapper claiming to handle lading of all libraries here <https://developers.google.com/chart/interactive/docs/drawing_charts#chartwrapper> - ChartWrapper constructor options claiming that you must load third-party libraries but not google.visualization libraries here <https://developers.google.com/chart/interactive/docs/reference#drawchart> I'm having problems loading a 'Map' chart type. When trying to load a map I receive the error 'object is not iterable (cannot read property Symbol(Symbol.iterator))' If I don't explicitly load the 'map' package. Here's an example piece of code that can be run to reproduce the issue. <html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js";></script> <script type="text/javascript"> google.charts.load('current'); // google.charts.load('current', { packages: ['map']}); google.charts.setOnLoadCallback(drawMap); function drawMap() { let mapWrapper = new google.visualization.ChartWrapper({ chartType: 'Map', dataTable: [ ['lattitude', 'longitude', 'label'], [-37.7647, 144.9393, 'hello'], [40.4165, -3.7026, 'hello2'] ], options: {'title': 'Stuff'}, container: document.getElementById('map_div') }); mapWrapper.draw(); } </script> </head> <body style="font-family: Arial;border: 0 none;"> <div id="map_div" style="width: 600px; height: 400px;"></div> </body> </html> If you run as-is, you will receive the error. If you uncomment the load call with the 'map' package then everything loads just fine. Is the Google Maps library considered a third-party library or is this a bug or am I missing something? Any help here would be greatly appriciated. Thank you! -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
