  • DxPolarChart<T>.Sorted Property

    Specifies whether series point connectors follow the visual argument order or original data source order. Applies only to line series.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    [DefaultValue(false)]
    [Parameter]
    public bool Sorted { get; set; }

    Property Value

    Type Default Description
    Boolean false

    true to connect series points in argument order; false to draw connectors in their original sequence from the data source.

    Remarks

    DxPolarChart automatically sorts the argument axis numerically or chronologically. The sort direction can be specified by the DxPolarChartArgumentAxis.Inverted property.

    Line series connectors follow the original data source order. If you plot unsorted data, the connectors may go backward or intersect. For example, if your dataset lists May 1st before April 18th, the corresponding connector line is plotted counterclockwise.

    This behavior can be useful for specific scenarios, such as plotting raw experimental data. If it does not match your intentions, set the Sorted property to true. This makes the chart render connectors based on the visual argument order (clockwise or counterclockwise).

    Note

    Setting the Sorted property to true forces the chart control to re-sort incoming data, even if it is already sorted. If your data is already sorted, leave it out or set it to false to improve performance.

        List<SaleInfo> DataSource { get; set; } = new List<SaleInfo>();

            DataSource = Data.Sales.GetMonthlySales();
        }
    }
    

    Sorted and unsorted charts

    Note the following limitations for the Sorted property:

    • While this property can be used with all chart types, it only affects the appearance of line series.
    • Automatic sorting of series points works only for numeric or date arguments. Line series with string arguments remain unchanged, regardless of this property’s value.
