Assign different fonts to the Points Labels on Line Graph

[CS]

Hi,

I am Tchart5x user.

I have a requirement in which I need to show the point labels in different fonts.
I am able to set the different colors using .Series(0).PointColor(0) property.

Is there any way to set different fonts for the points ?


Thanks,
Kailas

Hi Kalias,

I'm afraid this is not possible since the font property is a property for the whole series (TChart1.Series(0).Marks.Font) not for each value.
What you could do is to draw your text directly to the canvas like in the following example:

Code: Select all

Private Sub Form_Load()  
  TChart1.Aspect.View3D = False
  TChart1.Legend.Visible = False
  
  TChart1.AddSeries scPoint
  
  For i = 0 To 19
    TChart1.Series(0).Add Rnd * 100, "point nº" + Str$(i), clTeeColor
  Next i
  
  TChart1.Series(0).Marks.Font
End Sub

Private Sub TChart1_OnAfterDraw()
  Dim i As Integer
  For i = 0 To TChart1.Series(0).Count - 1
    TChart1.Canvas.Font.Size = (i Mod 10) + 10
    TChart1.Canvas.TextOut TChart1.Series(0).CalcXPos(i), TChart1.Series(0).CalcYPos(i), TChart1.Series(0).PointLabel(i)
  Next i
End Sub

I have requirement where I want to draw Rectangle around a text which I am plotting with help from you previously.

Can you help on this ?

Also I need to draw the text in between two point. I have attached attachment for more details.

Hello CS,

I have made a simple example for you using rectangle tool. Please check if next code works as you want:

Code: Select all

Private Sub Form_Load()
  TChart1.Aspect.View3D = False
  TChart1.Legend.Visible = False
 
  TChart1.AddSeries scLine
  TeeCommander1.Chart = TChart1

  For i = 0 To 19
    TChart1.Series(0).Add Rnd * 100, "point nº" + Str$(i), clTeeColor
  Next i
  TChart1.Environment.InternalRepaint
End Sub
Private Sub TChart1_OnAfterDraw()
  Dim i As Integer
  TChart1.Tools.Clear
  For i = 0 To TChart1.Series(0).Count - 1
    TChart1.Canvas.Font.Size = (i Mod 10) + 10
     With TChart1
        .Tools.Add tcRectangle
        .Tools.Items(i).asRectangle.Shape.CustomPosition = True
        .Tools.Items(i).asRectangle.AutoSize = True
        .Tools.Items(i).asRectangle.Shape.Transparency = 30
        .Tools.Items(i).asRectangle.Left = .Series(0).CalcXPos(i)
        .Tools.Items(i).asRectangle.Top = .Series(0).CalcYPos(i)
        .Tools.Items(i).asRectangle.Text = TChart1.Series(0).PointLabel(i)
    End With
  Next i
End Sub
Private Sub TChart1_OnScroll()
TChart1.Environment.InternalRepaint
End Sub

Private Sub TChart1_OnUndoZoom()
TChart1.Environment.InternalRepaint
End Sub
Private Sub TChart1_OnZoom()
  TChart1.Environment.InternalRepaint
End Sub

I hope will helps.

Hi ,

version 5 in which I don't see tcRectangle and TCommander

used "TeeChart5Activex.exe" for installation. We are calling the tchart componets from VB 6.

Thanks

Hi CS,

TeeCommander is not relevant for the example. You can use Annotation tools instead of Rectangle tools in v5 then. They work pretty much the same way.
