Hi,

We recently tried upgrading our versions of D3 and NVD3 but it causes our SVG charts to be rendered as blank on the PDF when converted. Debugging a little bit, I noticed that the HtmlToPdf.DebugConsole prints out the following message during the conversion:

Quote:
undefined:
JS ERROR:
TypeError: 'undefined' is not a function


The error doesn't occur when loaded through Chrome or Firefox, however. So I imagine there may be an issue executing the javascript during the PDF conversion but not when loading in a normal browser?

I've created an example page which shows the issue that can be downloaded through the link below:

[link removed since the issue has been resolved]

I'm using the latest posted version of EO.Pdf: 5.0.77.2

Thanks,

Lance

Hi,

We have looked into the problem. The root of the problem is we do not support Function.bind method. In order to resolve the issue, you can add the following code before you include any of D3 and NVD3 script code:

Code: JavaScript 
Function.prototype.bind = function(thisObj)
{
    var args = arguments;
    var fx = arguments.callee;
    return function()
    {
        fx.call(thisObj, args);
    }
}


Once you add this the conversion should complete without errors.

Thanks!
