To display DataSeries label as a tooltip on mouseover in a Line chart, use the following code:
•C#
DataSeries ds = new DataSeries()
{
ValuesSource = new double[] { 1, 2, 3, 2 },
ConnectionStrokeThickness = 5
};
ds.Loaded += (s, e) =>
{
PlotElement pe = s as PlotElement;
if (pe != null)
pe.MouseEnter += (sender, ea) =>
{
Debug.WriteLine("Series index = {0}", pe.DataPoint.SeriesIndex);
};
};
chart.Data.Children.Add(ds);
chart.ChartType = ChartType.Line;
