Google chart does not load in Firefox11

[Phanibhushan Reddy]

I have a simple line chart that works fine with IE but fails to load
in Firefox 11. Can someone help as to what is the issue and possible
trouble shooting steps?

Thanks,

Open the Firefox developer console (ctrl+shft+J) and reload the page.  You should see some sort of error there.

If you post your code or a link to the page, we can help you debug.

I'm having the same problem. We have several charts on one page and the last few do not load in FF11. Everything else works just fine.

When I looked at the Error Console, I see the error "the container is null or not defined"

Any suggestions would be really appreciated!

I do see an error in the console. Below is the abstract of the error. I am also attaching a screenshot.

m("google.visualization.arrayToDataTable",function(a,b){var c=new U,e,f,h;O(a)||d(n("Not an array"));if(0==a[D])return c;O(a[0])||d(n(Dg));var j=a[0][D];for(e=1;e<a[D];e++)(!O(a[e])||a[e][D]!=j)&&d(n(Dg));var o=(e=!b)?a[0]:[],s=e?a[fb](1,a[D]):a,w=[];for(f=0;f<j;f++){var z=cm;for(e=0;e<s[D];e++)if(h=s[e][f],N(h)){P(h)?z=cm:Q(h)?z=Xk:O(h)?z=qm:typeof h==Ch?z=Ch:(kn(h)&&d(n("Date and datetime column types are not supported")),d(n("Invalid value in "+e+xe+f)));break}w[f]=z}for(f=0;f<j;f++)c[Ed](w[f],

Hmm...I'm not familiar with the method you are using to create charts, but unless I miss my guess, that is the code for embedding charts, correct?

I tested it several times, and sometimes the charts draw, and sometimes they don't.  My suspicion is that one of two things is going on (maybe both):

1) There is a problem in the way the embedding code handles multiple embedded charts.  Fixing this would be out of your hands, so the solution is to use javascript to build the charts instead.

2) There is a problem with the interaction between the code that hides your page subsections and the drawing of the charts.  To render properly, the charts need to be drawn in a visible div (they can be hid immediately afterwards).  The chart embedding code doesn't expose anything that would allow you to determine when the charts are done drawing, so you can't fire the code to hide the div's with 100% certainty that it will work properly.  The solution, again, is to use javascript to build the charts.

As a test case, try disabling the code that hides your page sections and see what happens.  If the charts consistently draw properly, then the problem is likely #2.

Here is my code for the line chart.

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
          <script type="text/javascript">
                google.load("visualization", "1", {packages:["corechart"]});
                      google.setOnLoadCallback(drawChart);  
                           function drawChart()
                           {
   
   var data = google.visualization.arrayToDataTable([
['Month', 'Revenue', 'Expenses'],
['Jan', 123400.00, 98780.00],
['Feb', 114700.00, 109120.00],
['Mar', 134500.00, 101560.00],
['Apr', 111390.00, 99230.00],
['May', , ],
['June', , ]]);

var options = {
//title: 'Revenue-Expense Analysis'
};

        var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
         chart.draw(data, options);          
      }      
     
      </script>

I'm having troubles testing right now, but I assume this is because of the blank array elements - e.g, ['May', , ]. Replace with explicit nulls - ['May', null, null].

[Freddy]

But, it works fine in IE, placing null would make a difference in Firefox?

Thanks for the suggestion, let me try

FF11 (don't know about other browsers, didn't have a chance to check) doesn't parse ['a', , ] as a 3-element array. It thinks it's actually ['a', null] - a 2-elements array, which is bad input for arrayToDataTable.
