Hello, I have a real problem generating maps. Every time I try to do the natural breaks map i generate a new map different from the previous one. I can not explain it very well so, to show what I mean here we have two maps with the same data for the same year, all the same, and look:




You can see that it is not the same colour for the same provinces, even if the data are the same.

Anyone can help me? Thank you very much!

The reason that GeoDa's Natural Breaks maps can sometimes change slightly from time to time is that we use a randomized approximation algorithm to determine the Natural Breaks categories.  We do this so that the maps are always displayed very quickly.
