Hi,

I am using XY line Chart ,my requirement is that I want to assign Point lables for specific XY points .

This is just a sample Code

Code: Select all


For i = 0 To 10

    If pointlabel <> vbNullString Then
        TChart2.Series(0).AddXY i + 4, i + 3, PointLabe, clTeeColor
    Else
        TChart2.Series(0).AddXY i + 2, i + 5, "", clTeeColor
    End If

 Next

But problem is that it add the Point Lables on the X-Axis as Labels of Points.

is it possible that i directly send the sample project to Steema support Team.

VB .0
Windows Xp
TeeChart Pro 7

kindly help me in this regard

Hi Faizullah,

If you don't want the labels being displayed in the bottom axis you can use:

Code: Select all

    TChart1.Axis.Bottom.Labels.Style=talValue

If this doesn't solve the problem please post your example project at news://www.steema.net/steema.public.attachments newsgroup.

Hi Faizullah,

Ok, send it directly to me.

Hi Faizullah,

Thanks for the example. You have 2 options to achieve what you request:

1. Making you series marks visible, setting them to display the labels:

Code: Select all

   TChart1.Series(0).Marks.Visible = True
   TChart1.Series(0).Marks.Style = smsLabel

and hide the marks which don't have a customized label:

Code: Select all

Private Sub TChart1_OnGetSeriesMark(ByVal SeriesIndex As Long, ByVal ValueIndex As Long, MarkText As String)
    If (MarkText = CStr(TChart1.Series(SeriesIndex).YValues.Value(ValueIndex))) Then
        MarkText = ""
    End If
End Sub

2. Custom drawing on TeeChart's canvas using the OnAfterDraw event, i.e.:

Code: Select all

Private Sub TChart1_OnAfterDraw()
    TChart1.Canvas.TextOut TChart1.Series(0).CalcXPosValue(5), TChart1.Series(0).CalcYPosValue(10), "My custom text"
End Sub

Hi

Thanks ,my point label problem is solved with little modification

Code: Select all

Private Sub TChart1_OnGetSeriesMark(ByVal SeriesIndex As Long, ByVal ValueIndex As Long, MarkText As String)

    MarkText = CStr(TChart1.Series(SeriesIndex).PointLabel(ValueIndex))

    If UCase(MarkText) = "AB" 
      Exit Sub
    Else
      MarkText = ""
    End If

End Sub

But When at run time I Change some properties like Series Color the values are again shown on the points. How can I handle this situation.

Thanks and Regard

Hi,

have you tried to do a Repaint (TChart1.Repaint), after the changes has been applied ?

Hi

This situation is occur when I Change some properties like Series Color
from the ToolBar (TeeEditor) the values are again shown on the points.

On What Event of TeeChart I use TChart1.Repaint.

Thanks & Regards

Hi,

how about using the TeeCommander1_OnEditedChart() event ?

Posted: **Wed Jul 19, 2006 11:52 am**

Hi
Thanks for timely responce
This event

Code: Select all

Private Sub TeeCommander1_OnEditedChart()
  TChart1.Repaint
End Sub

works fine when we change some poperties from the ToolBar and after closing the ToolBar the point values disappered as my requirement.

But when we go to "Print" Option from the ToolBar again point values shown on the series and staight forwardly point values printed,when we print the Chart.

Kindly suggest a comprehensive solution for this problem.
very urgent

Thanks & Regards

Hi,

IN VB6.0 these kinds of problems are remedied by creating an EXE from your project and running it - have you tried doing that with your project?

Hi

Creating Exe of project and running, these problems are solved.

Thanks and Regard

Hi

When we drag the chart with mouse scrolling then the point labels that are shown on the points ,are still visible even if it is outside the chart fram.

how we hide the point label when it goes out of the chart displayed area .

Thanks & Regards

Hi Faizullah,

You can try using:

Code: Select all

    TChart1.Series(0).Marks.Clip = True
