AxisScaleBreakStyle.StartFromZero 属性

定义

命名空间:

System.Web.UI.DataVisualization.Charting

程序集:

System.Web.DataVisualization.dll

获取或设置一个 StartFromZero 枚举值，该值指示是否从零开始刻度分隔。

public:
 property System::Web::UI::DataVisualization::Charting::StartFromZero StartFromZero { System::Web::UI::DataVisualization::Charting::StartFromZero get(); void set(System::Web::UI::DataVisualization::Charting::StartFromZero value); };

public System.Web.UI.DataVisualization.Charting.StartFromZero StartFromZero { get; set; }

member this.StartFromZero : System.Web.UI.DataVisualization.Charting.StartFromZero with get, set

Public Property StartFromZero As StartFromZero

属性值

StartFromZero

一个 StartFromZero 枚举值，该值指示是否从零开始刻度分隔。

示例

下面的代码示例演示如何在控件添加到设计图面后启用和 Chart 自定义刻度中断。

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;  
}  

注解

如果 属性设置为 ，图表将自动计算是从序列中的最小值开始 Y 轴刻度最小值还是从零 StartFromZero Auto 开始。
