AxisScaleBreakStyle.CollapsibleSpaceThreshold 屬性

定義

在圖表上設定刻度斷線的門檻。

public:
 property int CollapsibleSpaceThreshold { int get(); void set(int value); };
public int CollapsibleSpaceThreshold { get; set; }
member this.CollapsibleSpaceThreshold : int with get, set
Public Property CollapsibleSpaceThreshold As Integer

屬性值

一個 integer 指定刻度劃分圖上空白閾值的數值。

範例

以下程式碼範例示範如何在控制項加入設計表面後啟用並自訂縮放中斷 Chart 。

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;
}

備註

此特性以Y軸刻度的百分比來衡量。 預設值設為25。 這表示序列中,若序列中差異至少25%,數據點會因尺度斷裂而被壓縮。
