Something a bit more advanced...
Using conditions in labelling
To understand this tip it is helpful if you have some knowledge of creating labels, especially labelexpressions in MapInfo Professional.
MapInfo Professional does not provide a direct way to label only certain records in a table. Oneworkaround to this is to create a selection from the table with the desired items to be labelled. You canadd this selection to the map window and turn labels on for it. However, there is another way!
Another possibility is to use a label expression that incorporates a condition within the Int() function. TheInt() function returns an integer, given a number. This will be used in a clever way to ensure only certainrecords in a table are labelled.
The following are some examples:
Given a column containing numeric values, the following expression will avoid labelling any value that iszero:
Left$ ( Str$ (COLUMN_NAME ) , Int (COLUMN_NAME > 0 ) * Len ( Str$ (COLUMN_NAME ) ) )
This basic technique can be used in a number of different ways. Here are some more examples:
1) The following expression will label any value above 50000.
Left$ ( Str$ ( COLUMN_NAME ) , Int (COLUMN_NAME > 50000 ) * Len ( Str$ (COLUMN_NAME )))
2) Given a character column containing classified data (“type” data), you could avoid the labelling of oneof the types. Let’s say a set of points represents different types of medical practices. The types are
GPs, paediatricians, cardiologists, neurologists, etc. The following expression will label all of the differenttypes except for GPs.
Left$ ( Str$ ( COLUMN_NAME ) , Int (COLUMN_NAME <> “GP ” ) * Len ( Str$ (COLUMN_NAME )))
3) Finally, in the above example, to label only the GPs, just change the <> expression to =
Left$ ( Str$ ( COLUMN_NAME ) , Int (COLUMN_NAME = “GP ” ) * Len ( Str$ (COLUMN_NAME )))
The trick to this is that this evaluation will result in a value of either
zero or one and this is multiplied by the result of the Len()
function. Therefore, if the result is zero then there will be no label
because the number of characters to return will be zero. If it is one
then a label is created.
A numeric column
