    In This Topic

    The range selection move resize drag tool allows the user to interactive drag and resize a range selection object (NRangeSelection). The following code shows how to create and configure a range selection move resize tool:

    C#
    Copy Code
    NChart chart = nChartControl1.Charts[0];
    NPointSeries point = new NPointSeries();
    point.Values.Add(10);
    point.Values.Add(20);
    chart.Series.Add(point);
    NRectangularCallout callout1 = new NRectangularCallout();
    callout1.UseAutomaticSize = true;
    callout1.Text = "Annotation 1";
    callout1.Orientation = 125;
    callout1.ArrowLength = new NLength(40, NGraphicsUnit.Point);
    callout1.Anchor = new NDataPointAnchor(point, 0, ContentAlignment.MiddleCenter, StringAlignment.Center);
    chart.ChildPanels.Add(callout1);
    NRectangularCallout callout2 = new NRectangularCallout();
    callout2.UseAutomaticSize = true;
    callout2.Text = "Annotation 2";
    callout1.Orientation = 45;
    callout2.ArrowLength = new NLength(40, NGraphicsUnit.Point);
    callout2.Anchor = new NDataPointAnchor(point, 1, ContentAlignment.MiddleCenter, StringAlignment.Center);
    chart.ChildPanels.Add(callout2);
    nChartControl1.Controller.Tools.Add(new NSelectorTool());
    nChartControl1.Controller.Tools.Add(new NCalloutDragTool());
    
    Visual Basic
    Copy Code
    Dim chart As NCartesianChart = CType(NChartControl1.Charts(0), NCartesianChart)
    Dim rangeSelection As New NRangeSelection
    rangeSelection.AllowHorizontalResize = True
    rangeSelection.AllowVerticalResize = True
    rangeSelection.ShowGrippers = True
    rangeSelection.Visible = True
    rangeSelection.HorizontalAxisRange = New NRange1DD(10, 15)
    rangeSelection.VerticalAxisRange = New NRange1DD(10, 15)
    chart.RangeSelections.Add(rangeSelection)
    Dim point As New NPointSeries
    point.UseXValues = True
    point.Values.Add(10)
    point.XValues.Add(10)
    point.Values.Add(20)
    point.XValues.Add(20)
    chart.Series.Add(Point)
    NChartControl1.Controller.Tools.Add(New NRangeSelectionMoveResizeTool())
    

    Now the user can move and resize the range selection.
