Google Charts API shows blank screen with $(document).ready method

Question

I\'ve got several functions that instantiate various charts using Google Charts API.

When I call them without jQuery\'s $(document).ready method, everything

Answer 1

Here is the paradigm I am using. Set a callback for the google.load method, and don't use the google.setOnLoadCallback at all (AFAIK this is not needed).

MyChart.prototype.render = function() {
    var self = this;
    google.load("visualization", 
                "1", 
                { callback: function() { self.visualize(); }, 
                  packages: ["corechart"] }
               );
}

MyChart.prototype.visualize = function() {

    var data = google.visualization.arrayToDataTable(
    [
        ['Year', 'Sales', 'Expenses'],  
        ['2004',  1000,      400],
        ['2005',  1170,      460],
        ['2006',  660,       1120],
        ['2007',  1030,      540]   
    ]);

    var options = {
        title: 'Company Performance',
        hAxis: {title: 'Year', titleTextStyle: {color: 'red'}}
    };

    var chart = new google.visualization.ColumnChart(document.getElementById("mychart_div"));    
    chart.draw(data, options);
}
