Series.Marks.Item Attributes not working

Hello,
I am having problems setting the Series.Marks.Item attribute. My graph is a 3d bar graph, plotting multiple series...
None of the following code snippets had any effect....
Code: Select all
Series(z).GetMarks().GetItem(x).SetVisible(bVisible)
or
Code: Select all
if (bVisible)
Series(z).GetMarks().GetItem(x).Show();
else
Series(z).GetMarks().GetItem(x).Hide();
or
Code: Select all
Series(z).GetMarks().GetItem(x).SetTransparent(!bVisible)
Is there something else that needs to happen to get the Series.Marks.Item attributes to act independent of the Series.Marks settings? I am using TeeChart Pro v2011.0.0.4.11109 32 VCL.
Thank you!

I'm trying this in VB6 and I find no problems with the following examples.
This two examples do the same. They show/hide the marks alternatively:
Code: Select all
Private Sub Form_Load()
Dim i, j As Integer
For i = 0 To 3
TChart1.AddSeries scBar
TChart1.Series(i).FillSampleValues
For j = 0 To TChart1.Series(i).Count - 1
TChart1.Series(i).Marks.Item(j).Visible = (j Mod 2 = 0)
Next j
Next i
End Sub
Code: Select all
Private Sub Form_Load()
Dim i, j As Integer
For i = 0 To 3
TChart1.AddSeries scBar
TChart1.Series(i).FillSampleValues
For j = 0 To TChart1.Series(i).Count - 1
If j Mod 2 = 0 Then
TChart1.Series(i).Marks.Item(j).Show
Else
TChart1.Series(i).Marks.Item(j).Hide
End If
Next j
Next i
End Sub
This one doesn't hide the marks at indexes 0,2,4,... like the above. It shows the text without shape for these marks.
Code: Select all
Private Sub Form_Load()
Dim i, j As Integer
For i = 0 To 3
TChart1.AddSeries scBar
TChart1.Series(i).FillSampleValues
For j = 0 To TChart1.Series(i).Count - 1
TChart1.Series(i).Marks.Item(j).Transparent = (j Mod 2 = 0)
Next j
Next i
End Sub
If you still have problems with it, could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Hello jbritt,
I have added more information that can help you to solve your problem. Concretely, I have converted the three examples that Yeray have suggested to VC++ 6.0, and code works me fine using last version of Activex:
Example with visible
Code: Select all
for(int i=0; i<3; i++)
{
m_ctrlChart.AddSeries(1);
m_ctrlChart.Series(i).FillSampleValues(10);
for(int j=0; j<m_ctrlChart.Series(i).GetCount();j++)
{
m_ctrlChart.Series(i).GetMarks().GetItem(j).SetVisible(j%2==0);
}
}
Code: Select all
for(int i=0; i<3; i++)
{
m_ctrlChart.AddSeries(1);
m_ctrlChart.Series(i).FillSampleValues(10);
for(int j=0; j<m_ctrlChart.Series(i).GetCount();j++)
{
if(j%2==0)
{
m_ctrlChart.Series(i).GetMarks().GetItem(j).Show();
}
else
{
m_ctrlChart.Series(i).GetMarks().GetItem(j).Hide();
}
}
}
Example with Transparent property:
Code: Select all
for(int i=0; i<3; i++)
{
m_ctrlChart.AddSeries(1);
m_ctrlChart.Series(i).FillSampleValues(10);
for(int j=0; j<m_ctrlChart.Series(i).GetCount();j++)
{
m_ctrlChart.Series(i).GetMarks().GetItem(j).SetTransparent(j%2==0);
}
}
I hope will helps.
Thanks,

Thanks for getting back to me so quickly.
I think I see the problem I was having. As new data comes in, I clear out the old set of data and add a new group of X, Y, Z data. The Series.Marks.Item attributes are also cleared at this time. I guess I'll have to set it again when I add the new data.
Thank you again for getting back so quickly on this!
