C#
//for input for pie chart..
            int i1 = int.Parse(textBox1.Text);
            int i2 = int.Parse(textBox2.Text);
            int i3 = int.Parse(textBox3.Text);
            int i4 = int.Parse(textBox4.Text);

            float total = i1 + i2 + i3 + i4;
            float deg1 = (i1 / total) * 360;
            float deg2 = (i2 / total) * 360;
            float deg3 = (i3 / total) * 360;
            float deg4 = (i4 / total) * 360;

            Pen p = new Pen(Color.Black, 2);

            Graphics g = this.CreateGraphics();

            Rectangle rec = new Rectangle(textBox1.Location.X + textBox1.Size.Width + 10, 12, 150, 150);

            Brush b1 = new SolidBrush(Color.Red);
            Brush b2 = new SolidBrush(Color.Blue);
            Brush b3 = new SolidBrush(Color.Black);
            Brush b4 = new SolidBrush(Color.BlueViolet);


            g.Clear(Form1.DefaultBackColor);
            g.DrawPie(p, rec, 0, deg1);
            g.FillPie(b1, rec, 0, deg1);
            g.DrawPie(p, rec, deg1, deg2);
            g.FillPie(b2, rec, deg1, deg2);
            g.DrawPie(p, rec, deg2 + deg1, deg3);
            g.FillPie(b3, rec, deg2 + deg1, deg3);
            g.DrawPie(p, rec, deg3 + deg2 + deg1, deg4);
            g.FillPie(b4, rec, deg3 + deg2 + deg1, deg4);
