    Tree tr;
    tr = dp.GetFormat(FPB_ALL, FOB_ALL, true, true);
    __int64 qColor;
    if(tr.Root.Line)
        qColor = tr.Root.Line.Color.nVal64;
    else if(tr.Root.Symbol)
        qColor = tr.Root.Symbol.EdgeColor.nVal64;
    else {
        out_str("plot type not having line nor symbol");
        return;
    }
    int nRefType = -1;
    if (okutil_get_col_by_ocolor(qColor, 0, NULL, &nRefType))
        printf("plot color by points, color linking type=%d\n", nRefType);
    else
        out_str("plot single color");
