The data series edited by the grid can be controlled in two ways:
Use the IncludedSeries and ExcludedSeries properties of the underlying DataSeriesGrid. The following example will display only the Values and Labels data series of a line series.
VB.NET
chartGridControl1.IncludedSeries = DataSeriesMask.Values Or DataSeriesMask.Labels chartGridControl1.ExcludedSeries = DataSeriesMask.None
For more information regarding data series filtering, please refer to the Basic Series Functionality topic.
Override the DataSeriesGrid class. The following code example demonstrates this technique:
VB.NET
... ' override the DataSeriesGrid Public Class MyDataGrid
Inherits DataSeriesGrid
Public Sub New()
End Sub
' override the GetDataSeries method and return only the series you want to edit in
' the order you want to edit them Public Overrides Function GetDataSeries(ByVal seriesBase As SeriesBase) As DataSeriesCollection
' for this example assume that the series is derived from Series Dim series As Series = CType(seriesBase, Series)
Dim col As DataSeriesCollection = New DataSeriesCollection()
' add fill effects, values, labels - reorder (if needed) must be made here
' !IMPORTANT - this method must return an aligned collection so force align if needed col.Align()
Return col End Function End Class ...
' define a member to keep your class instance Public myGrid As MyDataGrid
... ' handle form load event Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) ' create your datagrid derivative myGrid = New MyDataGrid()
' replace the data grid used by the ChartGridControl ChartGridControl1.DataSeriesGrid = myGrid
' bind to the chart control ChartGridControl1.ChartControl = m_ChartControl End Sub
C#
... // override the DataSeriesGrid public class MyDataGrid : DataSeriesGrid { public MyDataGrid() { } // override the GetDataSeries method and return only the series you want to edit in // the order you want to edit them public override DataSeriesCollection GetDataSeries(SeriesBase seriesBase) { // for this example assume that the series is derived from Series Series series = (Series)seriesBase; DataSeriesCollection col = new DataSeriesCollection();
// add fill effects, values, labels - reorder (if needed) must be made here col.Add(series.Appearance.FillEffects); col.Add(series.Values); col.Add(series.Labels);
// !IMPORTANT - this method must return an aligned collection so force align if needed col.Align();
return col; } } ... // define a member to keep your class instance public MyDataGrid myGrid; ... // handle form load event private void Form1_Load(object sender, System.EventArgs e) { // create your datagrid derivative myGrid = new MyDataGrid();
// replace the data grid used by the ChartGridControl ChartGridControl1.DataSeriesGrid = myGrid;
// bind to the chart control ChartGridControl1.ChartControl = m_ChartControl; }
