Consider this type of diagram:
 
Clearly, the coloring is wrong. I've tried playing with SetColorEach() and SetLegendVisible() but with no success. Digging into the source code reveals the issue. UpdateDiagram() does not check for the above! Palette index should be reset for each series!
 
void CXTPChartContent::UpdateDiagram()
{
    int i;
    int nIndex = 0;
    for (i = 0; i < GetSeries()->GetCount(); i++)
    {
        CXTPChartSeries* pSeries = GetSeries()->GetAt(i);
        if (!pSeries->IsVisible())
            continue;
        if (!pSeries->GetStyle())
            continue;
        if (pSeries->GetStyle()->IsColorEach())
        {
            for (int j = 0; j < pSeries->GetPoints()->GetCount(); j++)
            {
                pSeries->GetPoints()->GetAt(j)->m_nPaletteIndex = nIndex++;
            }
        }
        else
        {
            pSeries->m_nPaletteIndex = nIndex++;
        }
    }
}

And... just as usual the most critical functions are not virtual. Unbelievable! :(
 
XTPChartContent.h:
void UpdateDiagram();
CXTPChartDeviceContext* CreateDeviceContext(CXTPChartContainer* pContainer, HDC hDC, CRect rcBounds, BOOL bWindowDC);

While I'm at it, how do you set a title text above/under each pie?
