MFC使用TeeChart8控件画三维曲面时，出现“类型不匹配”问题，怎样解决！

Question

请教下大家TeeChart8画三维曲面的时候为什么提示：类型不匹配呀，下面是我的代码

m_chart.RemoveAllSeries();

    m_chart.AddSeries(scIsoSurface);

    CSeries linSeries = ((CSeries)m_chart.Series(0));

    ((CIsoSurfaceSeries)linSeries.get_asIsoSurface()).put_IrregularGrid(true);

    double r = 5;
    for (double i = -r; i <= r; i += 0.1)
    {
        for (double j = -r; j <= r; j += 0.1)
        {
            double k = r * r - i * i - j * j;
            if (k >= 0)
            {
                k = sqrt(k);
                ((CIsoSurfaceSeries)linSeries.get_asIsoSurface()).AddXYZ(i, j, -k, NULL, NULL);
            }
        }
    }

从TeeChart8.ocx库导入的头文件.h有问题，从网上下载了完整的类库包（.h.cpp），已解决！
