Hello Stata Community,

I am currently using STATA/SE 14 to analyze social expenditure at the regional level across 14 different countries in Europe, Asia, and North America from 1990 to 2017. I am analyzing the variation in social expenditure across regions in the 14 chosen countries and I have decided to create maps using different shapefiles for each of the 14 countries studied. For each individual map, I have chosen to divide the data into octiles, but is there any chance I can create specific boundaries that can apply to all maps I create? In other words, is there any chance that when using the spmap command I can specify what the boundaries of each octile should be? I would just like to create a general "quantile scheme" for all the maps I create to follow.

Thanks in advance for your help!
