Time Series Chart (Scrubbing across line values not working)

[arinhouck]

I have 3 labels, and I have built a computed property called graphPoint on a model and did a Ember.computed.maBy('objArray', 'graphPoint') and used Ember.computed.union(...). However my graph on hover does not give me that hover value. It puts these little dots on each ends of the lines only.

graphPoint: Ember.computed('country', 'percentage', 'effectiveDate', function() {
    return {
      value: this.get('percentage'),
      label: `Rate (${this.get('country')})`,
      time: d3.time.format.iso.parse(this.get('effectiveDate'))
    };
  })

I can only make this work if I manually create an mock array like in documentation and load in.

FYI @shiller-addepar : in case you might have touched the responsible code with your recent time series chart changes
