Hi,
Is there an example how to set tooltip text in a pie, from MFC?
I read something about OnGetText event and GetMark but I can't really understand how.
I am using TChartProAtvicex control v6.

Hi Jan,
to change the text of the Marks in VC++ you can use similar code to the following in the OnGetMarkText event :
Code: Select all
CString strLabel(*LabelText);
strLabel = "My cutom Label";
strLabel.SetSysString(LabelText);

Hi Jan,
sorry, just a modification :
Code: Select all
void CGetXSeriesMarksDlg::OnOnGetSeriesMarkTchart1(long SeriesIndex, long ValueIndex, BSTR FAR* MarkText)
{
CString strLabel(*MarkText);
strLabel = "My cutom Label";
strLabel.SetSysString(MarkText);
}

Hi,
I tried this. It just changes the label of the pie slices.
I whant to have a yellow tooltip that is displayed if uses puts mouse over the pie slies.
Pies are somettimes small, and the short text can be hard to understand. So I would like to display a longer description if user put mouse over whatever he dont understand.

I tried to oerwrite "OnOnMarkTipToolGetTextTchart"
without any result.
Id did not display any tooltip at all. Is it need to turn on tooltip somewhere?

Hi -

The following code works as expected here:
Code: Select all
void CVCplus60TESTAXv6Dlg::OnShowWindow(BOOL bShow, UINT nStatus)
{
CDialog::OnShowWindow(bShow, nStatus);
m_Chart1.AddSeries(scPie);
m_Chart1.Series(0).FillSampleValues(10);
m_Chart1.GetTools().Add(tcMarksTip);
m_Chart1.GetTools().GetItems(0).GetAsMarksTip().SetSeries(COleVariant("Series0"));
m_Chart1.Series(0).GetMarks().SetVisible(false);
}
BEGIN_EVENTSINK_MAP(CVCplus60TESTAXv6Dlg, CDialog)
//{{AFX_EVENTSINK_MAP(CVCplus60TESTAXv6Dlg)
ON_EVENT(CVCplus60TESTAXv6Dlg, IDC_TCHART1, 37 /* OnMarkTipToolGetText */, OnOnMarkTipToolGetTextTchart1, VTS_I4 VTS_PBSTR)
//}}AFX_EVENTSINK_MAP
END_EVENTSINK_MAP()
void CVCplus60TESTAXv6Dlg::OnOnMarkTipToolGetTextTchart1(long Tool, BSTR FAR* Text)
{
CString strLabel(*Text);
strLabel += " custom";
strLabel.SetSysString(Text);
}

I can't find the definition for tcMarksTip.
However it is listed in the manual.
TeeChartDefines.h
// EToolClass
const unsigned long tcCursor = 0;
const unsigned long tcDragMarks = 1;
const unsigned long tcAxisArrow = 2;
const unsigned long tcDraw = 3;
const unsigned long tcHints = 4;
const unsigned long tcColorband = 5;
const unsigned long tcColorLine = 6;
const unsigned long tcRotate = 7;
tcMarksTip = 8

Hi, Found the constant in manual. Not existing in headerfiles!
So now my tooltip is working. BUT! Major problem, it is one tooltip for hole Pie. I whant to display different tooltip for each item in a serie.
How can I do that?

From help:
Not all development environments support the direct call of TeeChart's Enum constants by name. See note on use of Enum constants for VBScript, MS VC++.
Integer Values:
tcCursor = 0
tcDragMarks = 1
tcAxisArrow = 2
tcDraw = 3
tcHints = 4
tcColorband = 5
tcColorLine = 6
tcRotate = 7
tcMarksTip = 8
tcChartImage = 9
tcAnnotate = 10
tcPageNumber = 11
