The data for the point data format is accessed by series. A series can be added or removed using the Chart3DPointSeries Collection Editor at design time or programmatically using AddSeries and RemoveSeries method of the Chart3DDataSetPoint class. For more information on accessing the Chart3DPointSeries Collection Editor, see Chart3DPointSeries Collection Editor.

The PointSeries Collection

Individual series are accessed via the SeriesCollection property of the Chart3DDataSetPoint object. The number of points in the series can be determined via the read-only Count property.

The Points property of Chart3DPointSeries class gives access to the points array of the series. It returns array of Chart3DPoint that represent coordinates of data points. To set new data points for the series, assign Points property to the new array of Chart3Dpoint.

Examples

The following creates point dataset and adds two series to it:

To write code in Visual Basic

Dim pointset As Chart3DDataSetPoint
pointset = new Chart3DDataSetPoint()
Dim len As Integer = 20
Dim i As Integer
Dim points1(len) As Chart3DPoint
Dim points2(len) As Chart3DPoint
Dim c, s As  Double
 
For i = 0 To 20
  c = Math.Cos(i * Math.PI * 2 / len)
  s = Math.Sin(i * Math.PI * 2 / len)
  points1(i) = New Chart3DPoint(s, c, 0)
  points2(i) = New Chart3DPoint(s, 0, c)
Next
 
pointset.AddSeries( points1)
pointset.AddSeries( points2)
                                        
' transfer dataset to the chart and select
scatterC1Chart3D1.ChartGroups(0).ChartData.Set = pointset
C1Chart3D1.ChartGroups(0).ChartType = Chart3DTypeEnum.Scatter

To write code in C#

Chart3DDataSetPoint pointset = new Chart3DdataSetPoint();
int len =21;
Chart3DPoint[] points1 = new Chart3DPoint[len];
Chart3DPoint[] points2 = new Chart3DPoint[len];
double c, s;
                                        
for( int i=0; i<len; i++)
{
  c = Math.Cos( i * Math.PI*2 / len);
  s = Math.Sin( i * Math.PI*2 / len);
  points1[i]=new Chart3DPoint(s, c, 0);
  points2[i]=new Chart3DPoint(s, 0, c);
}
                                        
pointset.AddSeries( points1);
pointset.AddSeries( points2);
                                        
// transfer dataset to the chart and select scatter
C1Chart3D1.ChartGroups[0].ChartData.Set = pointset;
C1Chart3D1.ChartGroups[0].ChartType = Chart3DTypeEnum.Scatter;

The following sets up a new array of data points to the first series:

To write code in Visual Basic

Dim pts(1) As Chart3DPoint
pts(0) = New Chart3DPoint( 0, 0, -1)
pts(1) = New Chart3DPoint( 0, 0, 1)
pointset.SeriesCollection(0).Points = pts

To write code in C#

Chart3DPoint[] pts = new Chart3DPoint[2];
pts[0] = new Chart3DPoint( 0, 0, -1);
pts[1] = new Chart3DPoint( 0, 0, 1);
pointset.SeriesCollection[0].Points = pts;
