Microsoft Charting 4.0 – Ploting a circle getting started

Posted: 2011-11-30 in .Net, Code and Computers

Ms charting is now included in the 4.0 library. This basically means to get started you no longer need to download anything special, even so you should download the older MS examples (found here). Its for VS2008 but the upgrade will go mostly smoothly, you will need to upgrade the solution to 4.0 framework to fix the missing references.


First create a new window form application.
DO NOT use WPF atm as it requires the wpf toolkit and do not use ASP .Net as the web.config requires a lot of hacking (contry to what MS and Scott will tell you). For now lets keep it simple.

Open the Form1 window designer and drag in the chart control found under data from the toolkit. If you dont’ have it check your project is set to build for .Net 4.0 framework (not client)

Open the Form1.cs code page and drop in the code below.
Comments: Everything in charts are controlled by its added series. You control types and everything


using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;
using System.Linq;

namespace WindowsFormsApplication1
    public partial class Form1 : Form
        public Form1()
        public void ChartType()
            //set it to fill for now
            chart1.Dock = DockStyle.Fill;

            //Clear anything that was there

            // Create a data series
            Series series1 = new Series();

            // Add data points to the first series
            series1.ChartType = SeriesChartType.FastLine;
            //get the points
            List<Tuple<double, double>> points = GetCircle(5);

            //add via looping
            //foreach (Tuple<double, double> xy in points)
            //    series1.Points.AddXY(xy.Item1, xy.Item2);

            //add with databind with linq for help
            series1.Points.DataBindXY(points.Select(e => e.Item1).ToList(), points.Select(e => e.Item2).ToList());

            // Add series to the chart


        private List<Tuple<double, double>> GetCircle(float radius)
            List<Tuple<double, double>> list = new List<Tuple<double, double>>();
            for (double i = 0.0; i < 360.0; i += 0.1)
                double angle = i * System.Math.PI / 180;
                double x = (radius * System.Math.Cos(angle));
                double y = (radius * System.Math.Sin(angle));
                list.Add(new Tuple<double, double>(x, y));

            return list;
