Re: [Qgis-user] Shapefiles with all numeric attribute names don't classify right?
Agreed, don't start field names with numbers. (from ESRI, but I think should apply equally to shapefiles used in QGIS): http://support.esri.com/cn/knowledgebase/techarticles/detail/23087 Phil On Tue, May 10, 2016 at 1:55 PM, Anita Graser wrote: > Hi Ian, > If I remember correctly, Shapefile attribute names must not start with a > number.

Hi Ian, If I remember correctly, Shapefile attribute names must not start with a number. Im not sure why this is but I think that could be part of the issue.

[Qgis-user] Shapefiles with all numeric attribute names don't classify right?
I have a shapefile with a bunch of attributes called 1980,1990,2000, etc to represent the years the data is for. They are integers (if that matters) but when I try to use them in a Qgis (2.14.2-Essen) the styler recognises them as numeric but when I try to produce a graduated style all the classes are set to -2147483648 - -2147483648. If I rename the attribute to 1980_inc or inc1980 the classifier is happy and everything works as I expect. Does anyone know what might be going on?
