Google Chart error: b.L is not a function

Question

I did a little page with 3 graphics using the Google API.

Everything worked perfectly. However from one moment to the other crashed.

In the chart of the place appears this message: bL is not the function

Does someone can explain to me why this happens?

My example working:

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script>
    google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
     var data = new google.visualization.DataTable();
        data.addColumn('string', 'Date');
        data.addColumn('number', '2015');
        data.addColumn('number', '2014');
        data.addRows([
    ['Jan', 197680, 241921],
    ['Fev', 183619,205572],
    ['Mar', 205643,214666],
    ['Abr', 205643,202097],
    ['Mai', 0,210007],
    ['Jun', 0,202434],
    ['Jul', 0,217502],
    ['Ago', 0,175038],
    ['Set', 0,206510],
    ['Out', 0,209802],
    ['Nov', 0,197122],
    ['Dez', 0,162796]

]);

        var options = {
          title: 'Energia 2014/2015',
          titleTextStyle: {color: 'white', fontSize: '18'},
          chart_M: 'function',
          legend: {textStyle: {color: 'white'}},
          colors: ['#0099FF', '#11334c'],
          backgroundColor: "transparent",
          hAxis: {title: '', 
            textStyle: {
            color: '#C8C8C8' 
            }},
                vAxis: {title: '', 
            textStyle: {
            color: '#C8C8C8' 
            }}

        };

      var chart = new google.visualization.ColumnChart(document.getElementById('chart_energy'));
        chart.draw(data, options);

      }

    </script>

This is how it was working.

From one moment to the other was so.

Answer 1

Your page contains the gauge, line and column charts. So I'm presuming you have calls to google.load("visualization", "1", {packages:["gauge"]}); as well, in addition to google.load("visualization", "1", {packages:["corechart"]});.

The different packages with separate load calls seemed to load fine until yesterday. But for some reason one or more packages aren't loading today which is why I was getting a similar exception.

Changing the separate load calls into one call like google.load("visualization", "1", {packages:["corechart","gauge"]}); should make it work.

Answer 2

I've got the same problem and it just started happening even though the chart was working earlier.

EDIT: I found that in my case google.load was called multiple times to load two different visualization packages. I've found out that if you load both packages at once it will resolve this error.
