Simple line graph charting

It was tinstaafl who put me on the right track. Click Here I did not know that .NET as of VS 2010 had a charting control!
OK, let’s get started! But the learning curve, is as always, a bit steep. MSDN does not seem to provide too much code, so I looked around on the net, but here they often make use of special graphics packages. So not much help either… After some fumbling around, I came up with the following easy ( I think ) code. Just start up a new windows form app and fill in the provided code in the Form.cs file. Enjoy!

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Graph = System.Windows.Forms.DataVisualization.Charting;

namespace WindowsFormsApplication1
    public partial class Form1 : Form
        Graph.Chart chart;

        public Form1()
            this.ClientSize = new System.Drawing.Size(750, 750);

        private void Form1_Load(object sender, EventArgs e)
            const int MaxX = 20;

            // Create new Graph
            chart = new Graph.Chart();
            chart.Location = new System.Drawing.Point(10, 10);
            chart.Size = new System.Drawing.Size(700, 700);

            // Add a chartarea called "draw", add axes to it and color the area black

            chart.ChartAreas["draw"].AxisX.Minimum = 0;
            chart.ChartAreas["draw"].AxisX.Maximum = MaxX;
            chart.ChartAreas["draw"].AxisX.Interval = 1;
            chart.ChartAreas["draw"].AxisX.MajorGrid.LineColor = Color.White;
            chart.ChartAreas["draw"].AxisX.MajorGrid.LineDashStyle = Graph.ChartDashStyle.Dash;

            chart.ChartAreas["draw"].AxisY.Minimum = -0.4;
            chart.ChartAreas["draw"].AxisY.Maximum = 1;
            chart.ChartAreas["draw"].AxisY.Interval = 0.2;
            chart.ChartAreas["draw"].AxisY.MajorGrid.LineColor = Color.White;
            chart.ChartAreas["draw"].AxisY.MajorGrid.LineDashStyle = Graph.ChartDashStyle.Dash;
            chart.ChartAreas["draw"].BackColor = Color.Black;
            // Create a new function series

            // Set the type to line      
            chart.Series["MyFunc"].ChartType = Graph.SeriesChartType.Line;

            // Color the line of the graph light green and give it a thickness of 3
            chart.Series["MyFunc"].Color = Color.LightGreen;
            chart.Series["MyFunc"].BorderWidth = 3; 

            //This function cannot include zero, and we walk through it in steps of 0.1 to add coordinates to our series
            for (double x = 0.1; x < MaxX; x += 0.1)
                chart.Series["MyFunc"].Points.AddXY(x, Math.Sin(x) / x);

            chart.Series["MyFunc"].LegendText = "sin(x) / x";

            // Create a new legend called "MyLegend".
            chart.Legends["MyLegend"].BorderColor = Color.Tomato; // I like tomato juice!

Hi ddanbe,

I'm glad you found a new toy to play with. :)

You may find these examples useful: Samples Environment for Microsoft Chart ControlsClick Here

The chart control was also made available for .Net 3.5 as a separate library.

From C# you could draw a chart in excel see example here C# 4.0 has improved interop syntax, but I could not find an example right away.

Can you offer any advice on using this code as a basis to plot data from a SQL server?

Never tried that myself, but this tutorial might help you out.
