Can’t show Charts

I can’t run the highcharts.js properly within the statistics page or any other page.
I’ve already uploaded the js file to /wp-content/plugins/highcharts-js/highcharts.js. The server returns a 200 status message, so I know the js file is being loaded. But for some reason the statics page displays the message “Charts cannot be displayed.”

On the options page, I’ve already checked the box for using the charts, can’t resolve the error here, please does any one knows whats wrong?

Thanks!
