title: Ng2-Admin template charts with DataLoader
body: <p>I'm trying to load data into some charts in the ng2-admin template using an API running on another server (or port to be exact).</p>
  
  <p>My code inside the lineChart.service.ts is as follows:</p>
  
  <pre><code>return {
    type: 'serial',
    theme: 'blur',
    marginTop: 15,
    marginRight: 15,
    responsive: {
      'enabled': true
    },
    dataLoader: {
      url: 'http://localhost:4000/reporting/temperatures',
      format: 'json',
      showErrors: true,
      noStyles: true,
      async: true
    },
  
    categoryField: 'MeasureMoment',
    categoryAxis: {
      parseDates: true,
      gridAlpha: 0,
      inside: true,
      color: layoutColors.defaultText,
      axisColor: layoutColors.defaultText
    },
    valueAxes: [
      {
        minVerticalGap: 50,
        gridAlpha: 0,
        color: layoutColors.defaultText,
        axisColor: layoutColors.defaultText,
        labelFunction: this.formatLabel
      }
    ],
    graphs: [
      {
        id: 'g0',
        bullet: 'none',
        useLineColorForBulletBorder: true,
        lineColor: colorHelper.hexToRgbA(graphColor, 0.3),
        lineThickness: 1,
        negativeLineColor: layoutColors.danger,
        type: 'smoothedLine',
        valueField: 'Temperature',
        fillAlphas: 1,
        fillColorsField: 'lineColor'
      }
    ],
    chartCursor: {
      categoryBalloonDateFormat: 'MM YYYY',
      categoryBalloonColor: '#4285F4',
      categoryBalloonAlpha: 0.7,
      cursorAlpha: 0,
      valueLineEnabled: true,
      valueLineBalloonEnabled: true,
      valueLineAlpha: 0.5
    },
    dataDateFormat: 'MM YYYY',
    export: {
      enabled: true
    },
    creditsPosition: 'bottom-right',
    zoomOutButton: {
      backgroundColor: '#fff',
      backgroundAlpha: 0
    },
    zoomOutText: '',
    pathToImages: layoutPaths.images.amChart
  };
  </code></pre>
  
  <p>This is not much other than the default page, except for the part of the data, where in the original template there is a dataProvider element with the data in it and I replaced that by a dataLoader, which I've used successfully before.</p>
  
  <p>I replaced the valueField and CategoryField values by the elements my API returns. As far as I know that should do the trick.
  When I reload the page I don't see any chart.</p>
  
  <p>I've tested the API, which returns data. I added a log row to the console every time the API is called showing a request is made. I see no requests being made when the ng2-admin page reloads. </p>
  
  <p>When I make some error and see an error message I could look into that, but there's no error message whatsoever.</p>
  
  <p>I could use some help figuring this one out. If more information is needed  I'll be glad to share.</p>
  
  <p>Thanks!</p>
