DxChartSeriesPoint.HoverMode Property

Specifies series elements to be highlighted when a user pauses on a series point.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(ChartSeriesPointHoverMode.Point)]
[Parameter]
public ChartSeriesPointHoverMode HoverMode { get; set; }

Property Value

Type	Default	Description
ChartSeriesPointHoverMode	Point	A ChartSeriesPointHoverMode enumeration value.

Available values:

Name	Description	Image
Point	Only the point that a user hovers over changes its style.
AllPoints	All points in the series change their style.
AllPointsForArgument	The point that a user hovers over and all other points with the same argument change their style.
None	The point does not change its style when a user hovers over it.

Remarks

This property specifies the hover mode for all the points in a series. See the DxChartSeriesPoint component’s description for more information.

Note

If the DxChartSeriesPoint.HoverMode property is set to None, the point’s behavior depends on the series-level setting (the DxChartLineSeries.HoverMode property for line series).

The following code specifies hover mode for series and series points:

@using Chart.Data

<DxChart Data="@SalesData">
    @* ... *@
    <DxChartLineSeries Name="Total Sales"
                       ArgumentField="@((SaleInfo s) => s.City)"
                       ValueField="@((SaleInfo s) => s.Amount)"
                       SummaryMethod="Enumerable.Sum"
                       HoverMode="ChartContinuousSeriesHoverMode.NearestPoint">
            <DxChartSeriesPoint Visible="true"
                                HoverMode="ChartSeriesPointHoverMode.Point" />
    </DxChartLineSeries>
</DxChart>

@code {
    IEnumerable<SaleInfo> SalesData;

    protected override async Task OnInitializedAsync() {
        SalesData = await Sales.GetSalesAsync();
    }
}
