Re: Problem in Dynamic pie chat in Google chart

[asgallant]

I see two problems:

1) you named the function you want to call "initialize", but have a "drawVisualization" in the callback handler.  Change the callback to initialize.

2) when I put this in a fiddle and ran it, I got an error when using the query option you specified.  Commenting out that line fixed the problem.

Here's a working version of your code: http://jsfiddle.net/asgallant/Tm32g/

Hello,

I am new to Google Chart and I am trying create a dynamic pie chart in the dynamic webproject(JEE). I have read the tutorial (https://developers.google.com/chart/interactive/docs/queries) and copy the pie chart code in the google code play ground.

---

   function initialize() 

    {

      // Replace the data source URL on next line with your data source URL.

      // Specify that we want to use the XmlHttpRequest object to make the query.

      var opts = {sendMethod: 'xhr'};

      var query = new google.visualization.Query('https://docs.google.com/spreadsheet/tq?range=A%3AB&key=0Aq4N8GK8re42dHlGMG0wM00tdE5PVjJZellXTEhFNEE&gid=0&headers=-1', opts);

      

      // Send the query with a callback function.

      query.send(handleQueryResponse);

    }

    

    function handleQueryResponse(response)

     {

    

      if (response.isError()) 

      {

        alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());

        return;

      }

    

      var data = response.getDataTable();

      var chart = new google.visualization.PieChart(document.getElementById('chart_div'));

      chart.draw(data, {width: 400, height: 240, is3D: true});

    }

    google.setOnLoadCallback(drawVisualization);

    </script>

But it is not working and there is no piechart. Could please tell me where is the problem. My spreadsheet is https://docs.google.com/spreadsheet/ccc?key=0Aq4N8GK8re42dHlGMG0wM00tdE5PVjJZellXTEhFNEE

Thank you.
