Cannot read property 'arrayToDataTable' of undefined at Google Geo Charts

Question

so this is my set up on my index.html. the api key has been generated at console.developers.google.com and I don\'t think that it was causing an error. the problem

Answer 1

First, remove the parentheses in ...

google.charts.setOnLoadCallback(drawStuff) // not drawStuff()

When you have the parenthesis, you are passing the result of calling the function, but the API wants to be given a handler function (not its result).

Furthermore, instead of ...

["Code", "Name", "Value"],

...try using the label syntax, like so...

[{label: 'Code', type: 'string'},
{label: 'Name', type: 'string'},
{label: 'Value', type: 'number'}],

The API should be able to figure it out without this change, but this is a "just-in-case-its-needed" sort of change that also makes the code more self-documenting.

Hi try with this console online for web html js css :

google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawStuff);
      function drawStuff() {
        var data = google.visualization.arrayToDataTable([
            ["Code", "Name", "Value"],
            ["PH-14", "Autonomous Region in Muslim Mindanao (ARMM)", 1],
            ["PH-05", "Bicol (Region V)", 2],
            ["PH-02", "Cagayan Valley (Region II)", 3],
            ["PH-40", "Calabarzon (Region IV-A)",4 ],
            ["PH-13", "Caraga (Region XIII)", 5],
            ["PH-03", "Central Luzon (Region III)", 6],
            ["PH-07", "Central Visayas (Region VII)", 7],
            ["PH-15", "Cordillera Administrative Region (CAR)", 8],
            ["PH-11", "Davao (Region XI)", 9],
            ["PH-08", "Eastern Visayas (Region VIII)", 10],
            ["PH-01", "Ilocos (Region I)", 11],
            ["PH-41", "Mimaropa (Region IV-B)", 12],
            ["PH-00", "National Capital Region Pambansang Punong", 13],
            ["PH-10", "Northern Mindanao (Region X)", 14],
            ["PH-12", "Soccsksargen (Region XII)", 15],
            ["PH-06", "Western Visayas (Region VI)", 16],
            ["PH-09", "Zamboanga Peninsula (Region IX)", 17]
          ]);

          // Set chart options
          var options = {
            'region': 'PH',
            'resolution': 'provinces',
            'title': 'How Much Pizza I Ate Last Night',
            'width': 400,
            'height': 300
          };

        var chart = new google.visualization.GeoChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
