Sorting QlikView排序表达式与内部的IF表达式匹配

我正在尝试使用IF语句创建自定义排序表达式

我有以下IF表达式：

=IF(VOTA >= -15 AND VOTA <= 15, '0',
IF(VOTA >= -60 AND VOTA <= -16, '-1 to 0',
IF(VOTA >= -120 AND VOTA <= -61, '-2 to -1',
IF(VOTA >= -180 AND VOTA <= -121, '-3 to -2',
IF(VOTA >= -240 AND VOTA <= -181, '-4 to -3',
IF(VOTA >= -241, '-4+',
IF(VOTA >= 60 AND VOTA <= 16, '1 to 0',
IF(VOTA >= 120 AND VOTA <= 61, '2 to 1',
IF(VOTA >= 180 AND VOTA <= 121, '3 to 2',
IF(VOTA >= 240 AND VOTA <= 181, '4 to 3',
IF(VOTA >= 241, '4+'
)))))))))))

但是它仍然没有按要求排序。

我通过添加

Dual（'xx到xx'，n）

和数字排序，成功地将其排序

=IF(VOTA <= -241, Dual('-4+',-5),
IF(VOTA >= -240 AND VOTA <= -181, Dual('-3 to -4',-4),
IF(VOTA >= -180 AND VOTA <= -121, Dual('-2 to -3',-3),
IF(VOTA >= -120 AND VOTA <= -61, Dual('-1 to -2',-2),
IF(VOTA >= -60 AND VOTA <= -16, Dual('0 to -1',-1),
IF(VOTA >= -15 AND VOTA <= 15, Dual('0',0),
IF(VOTA <= 60 AND VOTA <= 16, Dual('0 to 1',1),
IF(VOTA <= 120 AND VOTA <= 61, Dual('1 to 2',2),
IF(VOTA <= 180 AND VOTA <= 121, Dual('2 to 3',3),
IF(VOTA <= 240 AND VOTA <= 181, Dual('3 to 4',4),
IF(VOTA >= 241, Dual('4+',5)
)))))))))))

=IF（VOTA=-240和VOTA=-180和VOTA=-120和VOTA=-60和VOTA=-15）和VOTA仅按VOTA排序不起作用？我还认为排序表达式的结果需要是一个有序列表。因此，我可能会尝试复制分类IF（）而不是执行match（）策略语句并用纯数字替换文本。如果（VOTA>=-15和VOTA=-60和VOTA=-120和VOTA
仅按VOTA排序不起作用？
你知道吗，我甚至没有尝试过这个！
=IF(VOTA <= -241, Dual('-4+',-5),
IF(VOTA >= -240 AND VOTA <= -181, Dual('-3 to -4',-4),
IF(VOTA >= -180 AND VOTA <= -121, Dual('-2 to -3',-3),
IF(VOTA >= -120 AND VOTA <= -61, Dual('-1 to -2',-2),
IF(VOTA >= -60 AND VOTA <= -16, Dual('0 to -1',-1),
IF(VOTA >= -15 AND VOTA <= 15, Dual('0',0),
IF(VOTA <= 60 AND VOTA <= 16, Dual('0 to 1',1),
IF(VOTA <= 120 AND VOTA <= 61, Dual('1 to 2',2),
IF(VOTA <= 180 AND VOTA <= 121, Dual('2 to 3',3),
IF(VOTA <= 240 AND VOTA <= 181, Dual('3 to 4',4),
IF(VOTA >= 241, Dual('4+',5)
)))))))))))
