Exemples
L’exemple de code suivant montre comment activer et personnaliser un scale-break une fois que le Chart contrôle a été ajouté à l’aire de conception.
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;
}
Remarques
Si la propriété a la StartFromZeroAutovaleur , le graphique calcule automatiquement s’il faut démarrer l’échelle minimale de l’axe Y à partir de la valeur la plus basse de la série ou de zéro.
