   Something like this:

void CMarkupTitleView::OnChartClick(NMHDR* /*pNMHDR*/, LRESULT* /*pResult*/)
{
	CPoint pt;
	GetCursorPos(&pt);
	m_wndChartControl.ScreenToClient(&pt);

	CXTPChartElement* pElement = m_wndChartControl.HitTest(pt);

	if (DYNAMIC_DOWNCAST(CXTPChartTitle, pElement))
	{
		CXTPChartTitle* pTitle = (CXTPChartTitle*)pElement;

		SetTitle(pTitle);
	}	
	else if (DYNAMIC_DOWNCAST(CXTPChartAxis, pElement))
	{
		CXTPChartAxis* pAxis = (CXTPChartAxis*)pElement;

		pAxis->GetTitle()->SetVisible(TRUE);
		pAxis->GetTitle()->SetText(_T("Clicked On Axis"));

		//SetTitle(pTitle);
	}
	else if (DYNAMIC_DOWNCAST(CXTPChartSeriesPoint, pElement))
	{
		CXTPChartSeriesPoint* pPoint = (CXTPChartSeriesPoint*)pElement;

		TRACE(_T("Clicked on point with value: %i and argument: %s\n"), (int)pPoint->GetValue(0), pPoint->GetArgument());
	}
	else
	{
		SetTitle(NULL);
	}
}
