Příklady

Následující příklad kódu ukazuje, jak povolit a přizpůsobit přerušení škálování po přidání ovládacího prvku do návrhové Chart plochy.

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

Poznámky

StartFromZero Pokud je vlastnost nastavena na Auto, graf automaticky vypočítá, zda se má spustit minimální měřítko osy Y od nejnižší hodnoty v řadě nebo od nuly.
