This widget displays XY points where X and Y are the values of the two input metrics and the value pairs are obtained by matching data series by timestamp.

XY Chart

The widget by default uses the first defined metric as X values and the second one as Y values.

Additional metrics can be added, but in this case a custom Data Transformer must be defined, this will use the additional metrics to calculate the new X and Y values. Here is an example of a Data Transformer that uses a third metric to transform the new X values.

exports.xyDataTranformer = function() {
  function XYDataTranformer() {}
  XYDataTranformer.prototype.transform = function(data, args) {
    // console.log(data);
    // console.log(args);
    for(let i in data){
      data[i].rpm= data[i].rpm * data[i].ratio;
    }
    return data;
  };
  return XYDataTranformer;
}();

You can also display a stream chart by defining on the X or Y metrics the Paired Data Field which can be the name of another metric or the name of the data field generated by the custom data transformer (e.g. width2).

Configuration

Template Syntax

Below you can find some examples of how to use the component within a template.


<!-- example with simple points -->
<xy-chart-widget [title]="'Temperature by Humidity'">
      <metric name="humidity"></metric>
      <metric name="temperature"></metric>      
</xy-chart-widget>

<!-- example with filled lines -->
<xy-chart-widget [config]="{showLines: true, baseAxis: 'Y', showTimestamps: true, height: '640px'}">
	<metric name="rpm" unit="rpm"></metric>
	<metric name="depth" unit="m"></metric>
</xy-chart-widget>

<!-- example with data transformer -->
<xy-chart-widget [title]="'Depth as a function of Width'" [config]="{dataTransformer: 'widthDataTranformer', showBullets: false, showLines: true, baseAxis: 'Y', showTimestamps: true}" [inputs]="{period: 'period'}">
	<metric name="width" unit="cm" [config]="{pairedField: 'width2'}"></metric>
	<metric name="depth" unit="m"></metric>
</xy-chart-widget>
