Realize custome line

[coldwind]

hello:
I got a question, That's how to realize custome line ?
Just like the color line in demo, but i need to add the custome label above the end of the line and make the solid line to be dotted line

Hello,

you can change the style of the ColorLine Pen by using the Pen.Style property, 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;
            colorLine.Pen.Style = Steema.TeeChart.Drawing.DashStyle.Dot;

            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");
        }
