gistfile1.cs

private void Form1_Load(object sender, EventArgs e)
{

// The Excel file name
string fileNameString = "\\temp.xls";

string sConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + 
    fileNameString + ";Extended Properties=\"Excel 8.0;HDR=YES\"";
OleDbConnection myConnection = new OleDbConnection( sConn );
myConnection.Open();

// The code to follow uses a SQL SELECT command to display the data from the worksheet.
// Create new OleDbCommand to return data from worksheet.
OleDbCommand myCommand = new OleDbCommand( "Select * From [6954$B1:D250]", myConnection );

// create a database reader    
OleDbDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection);

// Populate the chart with data in the file
chart1.DataBindTable(myReader, "hiduke");
//chart1.Series[0].ChartType = SeriesChartType.Line;


chart1.Series["svalue"].ChartType = SeriesChartType.Line;
chart1.Series["hvalue"].ChartType = SeriesChartType.Line;


// close the reader and the connection
myReader.Close();
myConnection.Close();
