Hi Eric,
you can customize the Mark text by using the GetSeriesMark event of the Series.
Please see the help for details.

Can you please give me some sample code?
Your think that is enought information from TChart Help.chm

Triggered on placing Mark for each Series Point. Use this method to modify the Mark Text content.public GetSeriesMarkEventHandler GetSeriesMark

Hi.

The following example uses series GetSeriesMarj event to customize individual mark text:

Code: Select all

        public Form1()
        {
            InitializeComponent();
            line1.Marks.Visible = true;
            line1.FillSampleValues();
        }

        private void line1_GetSeriesMark(Steema.TeeChart.Styles.Series series, Steema.TeeChart.Styles.GetSeriesMarkEventArgs e)
        {
            // mark displays point pct and value
            double value = series.YValues[e.ValueIndex];
            double pct = value/series.YValues.TotalABS;
            e.MarkText = value.ToString()+" " +pct.ToString("0.00 %"); 
        }
