Series Formatters

[sarah_hussain-1]

I'm trying to use the series.formatters attribute in the advanced visualisation editor.  I have built a simple bar graph which plots a metric against months of the year and I'd like to conditionally format the colours of the bars above a certain number.

Here is my code snippet:

{
  xAxis: {
    plotBands: [{
      to: 1546300800000,
      from: 1640995200000,
      label: {
        text: 'Covid'
      }
    }]
  },
  series: [{
    formatters: [{
      select: 'value >= 5500000',
      style: {
        color: 'orange'
      }
    }]
  }]
}

I can successfully create my x-band, and I do not seem to have errors with my formatters, but these won't apply. Can anyone see why it's not working?
