Winform Chart Control in C# Using MS Access Database

Today I am going to show you how to chart control in C# using MS Access Database

 

Your database is shown below:

 

 

 

Now create a new project.

Select chart

View Top 5 Record

private void chartcon1()
{
    if (connectiondb.State == ConnectionState.Closed)
    {
        connectiondb.Open();
    }
    str3 = "select top 5 SName,mark from tbl_result";
    com3 = new OleDbCommand(str3, connectiondb);
    OleDbDataAdapter da = new OleDbDataAdapter(com3);
    DataTable dt = new DataTable();
    da.Fill(dt);
    connectiondb.Close();
    string[] N = new string[dt.Rows.Count];
    int[] M = new int[dt.Rows.Count];
    for (int i = 0; i < dt.Rows.Count; i++)
    {
        N[i] = dt.Rows[i][0].ToString();
        M[i] = Convert.ToInt32(dt.Rows[i][1]);
    }
    chart1.Series[0].Points.DataBindXY(N, M);
}

 

View chart By Id

private void chart_by_id()
{
    if (connectiondb.State == ConnectionState.Closed)
    {
        connectiondb.Open();
    }
    str3 = "select Exam_date,mark from tbl_result where S_id='" + textBox5.Text.Trim() + "'";
    com3 = new OleDbCommand(str3, connectiondb);
    OleDbDataAdapter da = new OleDbDataAdapter(com3);
    DataTable dt = new DataTable();
    da.Fill(dt);
    connectiondb.Close();
    string[] N = new string[dt.Rows.Count];
    int[] M = new int[dt.Rows.Count];
    for (int i = 0; i < dt.Rows.Count; i++)
    {
        N[i] = dt.Rows[i][0].ToString();
        M[i] = Convert.ToInt32(dt.Rows[i][1]);
    }
    chart1.Series[0].Points.DataBindXY(N, M);
}

And View Chart By Date change Event

private void result_by_date()
{
    if (connectiondb.State == ConnectionState.Closed)
    {
        connectiondb.Open();
    }
    str3 = "select SName,mark from tbl_result where Exam_date='" + dateTimePicker2.Text.Trim() + "'";
    com3 = new OleDbCommand(str3, connectiondb);
    OleDbDataAdapter da = new OleDbDataAdapter(com3);
    DataTable dt = new DataTable();
    da.Fill(dt);
    connectiondb.Close();
    string[] N = new string[dt.Rows.Count];
    int[] M = new int[dt.Rows.Count];
    for (int i = 0; i < dt.Rows.Count; i++)
    {
        N[i] = dt.Rows[i][0].ToString();
        M[i] = Convert.ToInt32(dt.Rows[i][1]);
    }
    chart1.Series[0].Points.DataBindXY(N, M);
}

 

This is my simple attempt at understanding chart control. Full code is shown below.
