Cannot view chart

Hello, i get this error in the browser console when anytime that i load my page with a custom wpdatachart:

Uncaught TypeError: wdtObj is undefined
    <anonymous> /wp-content/plugins/wpdatatables/assets/js/wpdatatables/wdt.chartsRender.min.js?ver=3.4.2:5
    jQuery 2
        dispatch
        handle
wdt.chartsRender.min.js:5:28

This makes my chart doesn’t render and i cannot view it
How can i solve?

EDIT: I noticed that this happen just on the first time i get into the page, if i reload it, it shows me the chart.

EDIT: wdtObj.fnDraw() this is the indicted code (why wdtObj is undefined?)
