Hi there. I need some help. I am trying to make an tematic map and i want to enter at the value an interval. For example i want to dysplay all constructions that were made between 1980 and 2012 and i dont know what to write at the Value. I've tried to enter (1980,2012) but is not good
Under thematic Rule....enter the expression CONSTYR >= '1980' AND CONSTYR <= '2012'. Not sure what your field names are but substitute the property name as needed. This will query only those years between 1980 and 2012 from which you can change the color value.
