[Gvsig_english] FW: bugreport: symbols-quantities-intervals fail with negative values

[Benjamin Ducke]

Hi Sergio,

There is one problem with this work-around: the "Expression" type
symbology does not work with fields that were joined in from an
external table (it simply does not list joined fields).
Is this just a bug, or is there some other reason for this?

Best,

Ben

Hi Klaus,

A similar problem appeared in the Spanish user list, it may be a bug 
when second term of an interval has a negative value. We'll try to fix it.

For the moment, an alternative solution would be to make the same legend 
by creating different expressions with the "Expression" type legend, as:

-18<[field] &&  [field]<-2.555
-2.55<[field] &&  [field]<2.55
....

A little less "automatic", but it should work.

Thanks for this report. Regards.
