Przykłady

W poniższym przykładzie kodu pokazano, jak włączyć i dostosować podział skali po Chart dodaniu kontrolki do powierzchni projektowej.

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;  
}  

Uwagi

StartFromZero Jeśli właściwość jest ustawiona na Autowartość , wykres automatycznie obliczy, czy uruchomić minimalną skalę osi Y z najniższej wartości w serii lub od zera.
