Hi nefis,

as you can see in the Help, it says :

IDrawLine
Description
DrawLine is the Line component used by the DrawLineTool to draw custom lines on the Chart.
----------------------------------------
You can use the Canvas drawing to do exactly the same. Or
uou can also use the DrawLineTool to draw lines programatically.

but you didn't answer on my question
what the difference between IDrawLineTool.FromPoint (ToPoint) and IDrawLine.StartPos (EndPos) properties?
Actually, I understand what is IDrawLine.StartPos (EndPos) for.
what the purpose of IDrawLineTool.FromPoint (ToPoint) properties?

Actually, we would prefer it if people didn't shout in these forums

!

Why don't you have a look at the example of these properties in use that can be seen in the AXv6 Feature Demo under:
Welcome! -> Previous version -> New Chart Tools -> Draw Line

Is that Steema's way to treat customers? Blaming them with "souting" instead of mere answering a quistion?
Have you ever read user's postings?
I've asked a simple question

what the purpose of IDrawLineTool.FromPoint (ToPoint) properties?

to your information there is none (nada) examples on IDrawLineTool.FromPoint (ToPoint) properties. Help is no help too

Hi Nefis,

Please find following a VB example of IDrawLineTool.FromPoint and IDrawLineTool.ToPoint

Code: Select all

Private Sub Command1_Click()
With TChart1
    If .Tools.Items(0).asDrawLine.Selected <> -1 Then
        Label1.Caption = "FromPoint (" & .Tools.Items(0).asDrawLine.FromPoint.X & " , " _
        & .Tools.Items(0).asDrawLine.FromPoint.Y & ")" & "  ToPoint (" & .Tools.Items(0).asDrawLine.ToPoint.X & " , " _
        & .Tools.Items(0).asDrawLine.ToPoint.Y & ")"
    End If
End With
End Sub

Private Sub Form_Load()
With TChart1
    .AddSeries scLine
    .Series(0).FillSampleValues 20
    .Axis.Left.SetMinMax 200, 800
    .Tools.Add tcDrawLine
    .Tools.Items(0).asDrawLine.Series = .Series(0)
    .Tools.Items(0).asDrawLine.AddLine 3, 300, 5, 600
End With
End Sub

These properties are read-only properties which read the StartPos and EndPos of the selected line. The Help file will be updated to reflect this functionality.

Hi Christopher,

thanks for the answer.
actually, saying that the properties returns end points of currently selected line would do it just fine.
