This is somewhat a followup to my prior post and somewhat a new, but
related problem.
I ended up doing what I had proposed, which is I have a table that has
each sample value and location:
Location Value cat
a 3.1 1
b 2.1 2
a 1.1 3
c 4.1 4
etc.
Then I have linked each vector point to multiple categories by using
v.edit map=foo layer=1 where="cat==1" type=point tool=catadd cat=3
(for example) So then I have an vector point that has a cat of both 1
and 3. So far so good.
If I then try to display Label vectors using Value for the attribute,
it works fine. Each value is displayed separated by a slash "/".
The problem is if I try to use a SQL query, it is not working as
expected. I think that what it is doing is just applying the test to
the first value, then showing or hiding the other values based on that
first test (although I am not 100% sure that is what it is doing).
So, for example, if I were to do Use SQL query: Value > 2.0 it would
draw a label like this: 3.1/1.1 And if I were to use a query of
Value < 2.0 it would not display anything. What I want it to do is to
show all values that are actually greater than 2. and not to display
the others.
Any suggestions of what it is doing, or what I can do about it?
I am using 6.4 RC3 on a Mac, and using sqlite for my db.
If I connect to the db just using the command line to connect to
sqlite, then the query works as expected.
As a secondary question, is it possible to change the "/" separator
that is used in the labels? Where is that determined? Can I instead
make it "/n" and get each value below?
Thanks,
