Public Property StartFromZero As StartFromZero

Valore della proprietà

Valore StartFromZero di enumerazione che indica se avviare l'interruzione di scala da zero.

Esempio

Nell'esempio di codice seguente viene illustrato come abilitare e personalizzare un'interruzione di scala dopo l'aggiunta del Chart controllo all'area di progettazione.

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;
}

Commenti

Se la StartFromZero proprietà è impostata su Auto, il grafico calcolerà automaticamente se avviare il valore minimo della scala dell'asse Y dal valore più basso della serie o da zero.
