Public Property StartFromZero As StartFromZero

Waarde van eigenschap

Een StartFromZero opsommingswaarde die aangeeft of het schaaleinde van nul moet worden gestart.

Voorbeelden

In het volgende codevoorbeeld ziet u hoe u een schaaleinde inschakelt en aanpast nadat het Chart besturingselement is toegevoegd aan het ontwerpoppervlak.

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;
}

Opmerkingen

Als de StartFromZero eigenschap is ingesteld op Auto, wordt in de grafiek automatisch berekend of de minimumschaal van de Y-as moet worden gestart vanaf de laagste waarde in de reeks of vanaf nul.
