If the table or table equivalent has multiple vertical dimensions, the current column segment will include
only rows with the same values as the current row in all dimension columns except for the column showing
the last dimension in the inter field sort order. The inter field sort order for pivot tables is defined simply by
the order of the dimensions from left to right. For other chart types this can be manipulated in the Chart
Properties: Sort dialog.
Specifying an offset greater than 1 lets you move the evaluation of expression to rows further down the current
row. A negative offset number will actually make the below function equivalent to a above function
with the corresponding positive offset number. Specifying an offset of 0 will evaluate the expression on the
current row. Recursive calls will return NULL.
By specifying a third parameter n greater than 1, the function will return not one but a range of n values, one
for each of n table rows counting downwards from the original cell. In this form, the function can be used as
an argument to any of the special Chart Range Functions (page 809).
Examples:
below( sum( Sales ))
below( sum( Sales ), 2 )
below( total sum( Sales ))
rangeavg
(below(sum(x),1,3))
returns an average of the three results of the sum(x) function evaluated on the
three rows immediately below the current row.
top([ total ] expression [ , offset [,n ]])
Returns the value of expression evaluated with the chart's dimension values as they appear on the first row
of the current column segment in a table or, in the case of bitmap charts, in the chart's straight table equivalent.
If the chart is one-dimensional or if the expression is preceded by the total qualifier, the current column segment
is always equal to the entire column.
If the table or table equivalent has multiple vertical dimensions, the current column segment will include
only rows with the same values as the current row in all dimension columns except for the column showing
the last dimension in the inter field sort order. The inter field sort order for pivot tables is defined simply by
the order of the dimensions from left to right. For other chart types this can be manipulated in the Chart
Properties: Sort dialog.
Specifying an offset greater than 1 lets you move the evaluation of expression down to rows below the top
row. A negative offset number will actually make the top function equivalent to a bottom function with the
corresponding positive offset number. Recursive calls will return NULL.
By specifying a third parameter n greater than 1, the function will return not one but a range of n values, one
for each of the first n rows of the current column segment. In this form, the function can be used as an argument
to any of the special Chart Range Functions (page 809).
Examples:
sum( Sales ) / top( sum( Sales ))
top( sum( Sales ), 2 )
top( total sum( Sales ))
rangeavg
(top(sum(x),1,5))
returns an average of the results of the sum(x) function evaluated on the five
top rows of the current column segment.
bottom([ total ] expression [ , offset [,n ]])
