Webix Jet with Highcharts / php

Webix JS
1

Hi,
anybody worked with Webix Jet in combination with Highcharts?
There is the highcharts helper

but I can’t get it working when I want to load data from a database by using

  $.getJSON("http://localhost/logintest/assets/data.json", function (data) {
        // Populate series
        for (i = 0; i < data.length; i++){
            studio_duration_json.push([Date.parse(data[i].start_date), parseFloat(data[i].duration));
        }
    });

Has anybody tried that and got it working?

Thanks,
Martin
