Readout Properties

const shadedLayer = new ShadedLayer({
  ...
  readout: [
    {
      // array - full data array
      data,
      // number - rounding of data in the readout
      decimals,
      // boolean - does readout use linear interpolated between points
      interpolate,
      // string - leading readout text such as `Mean Temperature`
      prependText,
      // string - will be appended to the end of the data value (ie `mph`)
      units,
      // function - this will alter the default readout text for the value. It takes `value` as
      // an argument and should return a string
      valueFormatter
    }
