    Format the legend keys any way you want by using alias patterns.<br /> <br />

    Example: <code ng-non-bindable>{{metric.name}} - {{metric.label.instance_name}}</code><br />
    Result: &nbsp;&nbsp;<code ng-non-bindable>cpu/usage_time - server1-europe-west-1</code><br /><br />

    <strong>Patterns</strong><br />
    <ul>
      <li>
        <code ng-non-bindable>{{metric.type}}</code> = metric type e.g. compute.googleapis.com/instance/cpu/usage_time
      </li>
      <li>
        <code ng-non-bindable>{{metric.name}}</code> = name part of metric e.g. instance/cpu/usage_time
      </li>
      <li>
        <code ng-non-bindable>{{metric.service}}</code> = service part of metric e.g. compute
      </li>
      <li>
        <code ng-non-bindable>{{metric.label.label_name}}</code> = Metric label metadata e.g.
        metric.label.instance_name
      </li>
      <li>
        <code ng-non-bindable>{{resource.label.label_name}}</code> = Resource label metadata e.g. resource.label.zone
      </li>
