DxRangeSelectorChartValueAxis Class

Defines a value axis in the Range Selector’s DxRangeSelectorChart component.

Assembly: DevExpress.Blazor.v24.2.dll

Declaration

public class DxRangeSelectorChartValueAxis :
    DxSettingsComponent<RangeSelectorChartValueAxisModel>

Remarks

Use DxRangeSelectorChartValueAxis class APIs to manage the value axis in the Range Selector’s DxRangeSelectorChart component. The following properties are available:

Type | ValueType: Define the type of the value axis and assigned data source values.
MinValue | MaxValue: Specify the axis’s visual range.
LogarithmBase: Specifies the value to be raised to a power when DxRangeSelectorChart generates ticks for the value axis of the Logarithmic type.
Inverted: Specifies whether the value axis is inverted.

The value axis in the Range Selector’s DxRangeSelectorChart component does not support visual elements (for example, ticks or labels) and does not include any nested components.

Example

The following code snippet inverts the value axis in the Range Selector’s chart:

Range Selector - Inverted Value Axis

<DxRangeSelector Width="100%"
                 Data="@Data"
                 ValueChangeMode="RangeSelectorValueChangeMode.OnHandleMove">
    <DxRangeSelectorChart>
        @CreateChartAreaSeries(s => s.Y1)
        @CreateChartAreaSeries(s => s.Y2)
        @CreateChartAreaSeries(s => s.Y3)
        <DxRangeSelectorChartValueAxis Inverted="true" />
    </DxRangeSelectorChart>
    <DxRangeSelectorScale TickInterval="50" />
</DxRangeSelector>

@code {
    protected override void OnInitialized() {
        Data = RangeSelectorPointProvider.GetData();
    }

    private RenderFragment CreateChartAreaSeries(Expression<Func<Point, double>> valueField) =>
        @<DxChartAreaSeries ArgumentField="@(s => s.Arg)"
                            ValueField="@(valueField)">
        </DxChartAreaSeries>;
}

public interface IRangeSelectorPointProvider {
    public List<Point> GetData();
}

public class RangeSelectorPointProvider : IRangeSelectorPointProvider {
    public List<Point> GetData() {
        return new List<Point> {
            new Point { Arg = 10, Y1 = -12, Y2 = 10, Y3 = 32 },
            new Point { Arg = 20, Y1 = -32, Y2 = 30, Y3 = 12 },
            new Point { Arg = 40, Y1 = -20, Y2 = 20, Y3 = 30 },
            new Point { Arg = 50, Y1 = -39, Y2 = 50, Y3 = 19 },
            new Point { Arg = 60, Y1 = -10, Y2 = 10, Y3 = 15 },
            new Point { Arg = 75, Y1 = 10, Y2 = 10, Y3 = 15 },
            new Point { Arg = 80, Y1 = 30, Y2 = 50, Y3 = 13 },
            new Point { Arg = 90, Y1 = 40, Y2 = 50, Y3 = 14 },
            // ...
        };
    }
