member this.CollapsibleSpaceThreshold : int with get, set

Public Property CollapsibleSpaceThreshold As Integer

Property Value

Int32

An integer value that specifies the threshold of space on the chart at which scale breaks are drawn.

Examples

The following code example demonstrates how to enable and customize a scale break after the Chart control has been added to the design surface.

Imports System.Web.UI.DataVisualization.Charting  

Private Function AddChartData()   

    chart1.Series("Default").Points.Add(New DataPoint(1, 2))   
    chart1.Series("Default").Points.Add(New DataPoint(2, 4))   
    chart1.Series("Default").Points.Add(New DataPoint(3, 400000))   
    chart1.Series("Default").Points.Add(New DataPoint(4, 3))   

End Sub  

Private Function AddScaleBreaks()  

   ' Enable scale breaks.  
   chart1.ChartAreas("Default").AxisY.ScaleBreakStyle.Enabled = True   

   ' Show scale break if more than 25% of the chart is empty space.       
   chart1.ChartAreas("Default").AxisY.ScaleBreakStyle.CollapsibleSpaceThreshold = 25   

   ' Set the line width of the scale break.      
   chart1.ChartAreas("Default").AxisY.ScaleBreakStyle.LineWidth = 2   

   ' Set the color of the scale break.   
   chart1.ChartAreas("Default").AxisY.ScaleBreakStyle.LineColor = Color.Red   

   ' If all data points are significantly far from zero, the chart will calculate the scale minimum value.   
   chart1.ChartAreas("Default").AxisY.ScaleBreakStyle.StartFromZero = StartFromZero.Auto  

   ' Set the spacing gap between the lines of the scale break (as a percentage of the Y-axis).  
   chart1.ChartAreas["Default"].AxisY.ScaleBreakStyle.Spacing = 2;  

End Function

using System.Web.UI.DataVisualization.Charting  

private void AddChartData()  
{  
   chart1.Series["Series1"].Points.Add(new DataPoint(1, 2));  
   chart1.Series["Series1"].Points.Add(new DataPoint(2, 4));  
   chart1.Series["Series1"].Points.Add(new DataPoint(3, 400000));  
   chart1.Series["Series1"].Points.Add(new DataPoint(4, 3));  
}  

private void AddScaleBreaks()  
{  
   // Enable scale breaks.  
   chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.Enabled = true;  

   // Show scale break if more than 25% of the chart is empty space.  
   chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.CollapsibleSpaceThreshold = 25;  

   // Set the line width of the scale break.  
   chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.LineWidth = 2;  

   // Set the color of the scale break.  
   chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.LineColor = Color.Red;  

   // If all data points are significantly far from zero, the chart will calculate the scale minimum value.  
   chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.StartFromZero = StartFromZero.Auto;  

   // Set the spacing gap between the lines of the scale break (as a percentage of the Y-axis).  
    chart1.ChartAreas["ChartArea1"].AxisY.ScaleBreakStyle.Spacing = 2;  
}

Remarks

This property is measured as a percentage of the Y-axis scale. By default, its value is set to 25. This means that data points in a series that have a difference of at least 25% of the scale will be collapsed with a scale break.
