Is there a tool to draw shapes on a chart?

[WD_Gordon]

I have a chartwith a candle series. My employer wants me to add the capability to draw circles and ellipses on the candle chart. Is there such a tool?

Hi WD_Gordon!

I propos one solution, you can help.

You, can use events OnMouseUp, and OnMouseDown as next exemple:

OnMouseDown

Code: Select all

        private void tChart1_MouseDown(object sender, MouseEventArgs e)
        {
            Steema.TeeChart.Styles.Shape sh = new Steema.TeeChart.Styles.Shape(tChart1.Chart);
            sh.Style = ShapeStyles.Circle;
            sh.Transparent = true;
            sh.X0 = tChart1.Axes.Bottom.CalcPosPoint(e.X);
            sh.Y0 = tChart1.Axes.Left.CalcPosPoint(e.Y);

        }

OnMouseUp

Code: Select all

        private void tChart1_MouseUp(object sender, MouseEventArgs e)
        {
            
            ((Steema.TeeChart.Styles.Shape)tChart1[tChart1.Series.Count - 1]).X1 = tChart1.Axes.Bottom.CalcPosPoint(e.X);
            ((Steema.TeeChart.Styles.Shape)tChart1[tChart1.Series.Count - 1]).Y1 = tChart1.Axes.Left.CalcPosPoint(e.Y);
            tChart1[tChart1.Series.Count - 1].Repaint();
        }

You needs assign X0,Y0,X1,Y1 values,because you does not draw correct circle. If you would draw an ellipse, you just have to draw the circle lying.

Thanks,
