XValues プロパティ (XYPointSeries)

Visual Basic
C#

'Declaration
 
Public ReadOnly Property XValues As DoubleCollection

'使用法
 
Dim instance As XYPointSeries
Dim value As DoubleCollection
 
value = instance.XValues

public DoubleCollection XValues {get;}

x値が提供されていない場合は、データポイントのインデックスがx値に使用されます。

次のサンプルコードは、XValuesプロパティを使用します。

C#

plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series0);
plotArea.Series.Add(series1);

LabelArea label = new LabelArea();
label.Text = "XY Point Chart";
label.Location = new PointF(0.5f, 0.02f);
label.AlignmentX = 0.5f;
label.AlignmentY = 0.0f;

LegendArea legend = new LegendArea();
legend.Location = new PointF(0.98f, 0.5f);
legend.AlignmentX = 1.0f;
legend.AlignmentY = 0.5f;

ChartModel model = new ChartModel();
model.LabelAreas.Add(label);
model.LegendAreas.Add(legend);
model.PlotAreas.Add(plotArea);
chart2DControl1.Model = model;
