Hello!

One way of approaching this issue would be the following:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Series.Add(typeof(Line)).FillSampleValues();
      tChart1.Series.Add(typeof(Line)).FillSampleValues();

      tChart1.Chart.Listeners.Add(new ChangeEvent(tChart1.Chart));
    }


    public class ChangeEvent : ITeeEventListener
    {

      private Chart chart;
      public ChangeEvent(Chart c)
      {
        chart = c;
      }

      public void TeeEvent(TeeEvent e)
      {
        if(e is SeriesEvent)
        {
          SeriesEvent tmp = (SeriesEvent)e;
          if(tmp.Event == SeriesEventStyle.ChangeActive)
          {
            string text = "";
            foreach (Series s in chart.Series)
            {
              if(s.Active)
              {
                text += "series " + s.Title + " is active" + Utils.NewLine;
              }

              if(Utils.IsNullOrEmpty(text))
              {
                chart.Header.Text = "no active series";
              }
              else
              {
                chart.Header.Text = text;
              }
            }
          }
        }
      }
    }
