Hi

First you have to indicate that the X value of the serie is a DateTime, and then you can import the Chart. You can do something similiar as below code

Code: Select all

   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Line1.XValues.DateTime = True
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim ts As New Steema.TeeChart.Data.TextSource()
        Try
            Cursor = Cursors.WaitCursor
            ts.HeaderLines = 0
            ts.Separator = ","
            ts.Series = Line1
            ts.Fields.Add(0, "X")
            ts.Fields.Add(2, "Y")
            ts.LoadFromFile("c:\your_file.txt")
        Finally
            Cursor = Cursors.Default
        End Try
    End Sub
