How to customize the order of the legend in Chart?
The chart legend order can be customized through the FilterItems event of the legend. You can add the legend items to the ChartLegendItemsCollection class and dispaly the legend items in reversed order
C#
this.chartControl1.Legend.FilterItems +=new LegendFilterItemsEventHandler(Legend_FilterItems);
private void Legend_FilterItems(object sender, ChartLegendFilterItemsEventArgs e)
{
//This creates an new instance of the ChartLegendItemCollection
ChartLegendItemsCollection item = new ChartLegendItemsCollection();
for(int i=e.Items.Count - 1;i>=0;i--)
item.Add(e.Items[i]);
e.Items =item;
}
VB
Me.chartControl1.Legend.FilterItems +=New LegendFilterItemsEventHandler(Legend_FilterItems)
Private Sub Legend_FilterItems(ByVal sender As Object, ByVal e As ChartLegendFilterItemsEventArgs)
'This creates an new instance of the ChartLegendItemCollection
Dim item As ChartLegendItemsCollection = New ChartLegendItemsCollection()
Dim i As Integer
For i = e.Items.Count - 1 To 0 Step i - 1
item.Add(e.Items(i))
Next
e.Items =item
End Sub
