Can't get amCharts WordPress dataloader to work - wordpress

Question

I am trying to use Data Loader from amCharts in WordPress, but I have no success. I am starting with an default Stock Chart and replacing the JS dataset structure with the one from the github site. Then I change the corresponding field values but I always get an empty site. I am using a CSV file on the same server to make sure it is not an access to external sources problem.
Does someone maybe have a complete code?
Here is my not working code so far:
var chart = AmCharts.makeChart("chartdiv", {
