Hello,

You can draw text to the Chart using one of its Drawing events, and can use the position of Chart elements to draw text relative to them, e.g.

Code: Select all

        readonly ColorLine colorLine;

        public Form1()
        {
            InitializeComponent();

            var bar = new Bar(tChart1.Chart);
            bar.FillSampleValues();
            colorLine = new ColorLine(tChart1.Chart)
            {
                Axis = tChart1.Axes.Bottom,
                Value = 2.5
            };
            colorLine.Pen.Width = 3;
            colorLine.Pen.Color = Color.Red;

            tChart1.AfterDraw += TChart1_AfterDraw;
        }

        private void TChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.IGraphics3D g)
        {
            g.Font.Size = 16;
            g.TextOut(tChart1.Axes.Bottom.CalcXPosValue(colorLine.Value), tChart1.Axes.Left.IStartPos, "Hello");
        }
