title: How can I achieve timeline filter bar chart with NGX charts?
body: <p>I've been trying to figure out how to achieve the timeline for x-axis for NGX chart like in documentation demo page:
  <a href="https://swimlane.github.io/ngx-charts/#/ngx-charts/timeline-filter-bar-chart-demo" rel="nofollow noreferrer">https://swimlane.github.io/ngx-charts/#/ngx-charts/timeline-filter-bar-chart-demo</a></p>
  <p>But there isn't anywhere code how it was achieved, like in other ngx charts.</p>
  <p>I got the JSON and basics all working:</p>
  <pre><code>name: 'Temperature',
        series: [
          { value: 22, name: '2021-06-01 10:45:00+00' },
          { value: 33, name: '2021-06-01 11:14:44+00' },
          { value: 11, name: '2021-06-01 13:45:00+00' }, ... ]
  </code></pre>
  <p>But I don't seem to get anywhere without stackblitz code example like with other chart types and features.</p>
