    Adding Rows and Columns
    In This Topic

    To add rows to a chart group, do the following:

    Set the RowCount property to the new number of rows.

    If the data is irregularly-grid, set the RowDeltaArray property for the space between a new row and its predecessor.

    Set the Item property for each of the new points.

    For example, the following code adds a fourth row of three points to a ChartGroup:

    To write code in Visual Basic

    Visual Basic
    Copy Code
    With C1Chart3D1.ChartGroups(0).ChartData.SetGrid
      .RowCount = 4
      .Item(0, 3) = 5.17
      .Item(1, 3) = 5.84
      .Item(2, 3) = 6.33
    End With
    

    To write code in C#

    C#
    Copy Code
    C1Chart3D1.ChartGroups[0].ChartData.SetGrid.RowCount = 4;
    C1Chart3D1.ChartGroups[0].ChartData.SetGrid[0,3] = 5.17;
    C1Chart3D1.ChartGroups[0].ChartData.SetGrid[1,3] = 5.84;
    C1Chart3D1.ChartGroups[0].ChartData.SetGrid[2,3] = 6.33;
    

    New columns can be added in much the same way:

    Set the ColumnCount property to the new number of columns.

    If the data is irregularly-grid, set the ColumnDeltaArray property for the space between a new column and its predecessor.

    Set the Item property for each of the new points.
