JavaScript/jQuery PolarChart - valueAxis.visualRange

This property accepts one of the following:

• A two-item array

  Specifies the range's start and end. The array can contain a pair of numeric, string, or date-time values, depending on the axis's valueType. You can also set one of the array values to null to specify an open-ended range.

  index.js

  $(#polarChart).dxPolarChart({
      valueAxis: {
          visualRange: [50, 70]
      }
  })
  // Open-ended range
  $(#polarChart).dxPolarChart({
      valueAxis: {
          visualRange: [null, 70]
      }
  })

  Angular

  app.component.html

  <dx-polar-chart>
      <dxo-value-axis [visualRange]="[50, 70]" ></dxo-value-axis>
  </dx-polar-chart>
  <!-- Open-ended range -->
  <dx-polar-chart>
      <dxo-value-axis [visualRange]="[null, 70]" ></dxo-value-axis>
  </dx-polar-chart>

  })
  // Open-ended range
  $(#polarChart).dxPolarChart({
      valueAxis: {
          visualRange: { startValue: null, endValue: 70 }
      }
  })

• An object with the length and startValue or endValue

  Specifies the range using length and start or end values.

  index.js

  $(#polarChart).dxPolarChart({
      valueAxis: {
          visualRange: { startValue: 50, length: 20 }
      }
  })
  // or
  $(#polarChart).dxPolarChart({
      valueAxis: {
          visualRange: { endValue: 70, length: 20 }
      }
  })

  <dx-polar-chart>
      <dxo-value-axis [visualRange]="{ startValue: 50, length: 20 }" ></dxo-value-axis>
  </dx-polar-chart>
  <!-- or -->
  <dx-polar-chart>
      <dxo-value-axis [visualRange]="{ endValue: 70, length: 20 }" ></dxo-value-axis>
  </dx-polar-chart>

  If you specify only length, the component defines the endValue property as the largest scale value.

To specify the minimum visual range that a user can set, use the minVisualRangeLength property.

If the axis/scale displays numbers, set this property to a number:

length: 100 // a hundred axis/scale values

If the axis/scale displays date-time values, set it to an accepted string value or object that contains a field described further in this section:

length: 'day' // one day
length: { days: 2 } // two days
