Hi , I have introduced my self a couple of months ago and disapear for a while. I am doing my masters thesis on mapping malaria .I have a 5 year data and i was trying to show the trend by just creating different maps for each year but i wanted to determine one quartile from all the 5 year data. I have attached an image which shows the kind of thing i wanted to do. How can i do that?

Thank you so much in advance.

Well, it appears pretty straight forward, no? You have your malaria data by county or region, correct? Calculate quartiles for the entire dataset (per year or decade, that's up to you), assign a quartile range or number for each region/county (depending on where the data point falls) and then symbolize on that attribute. Does that make sense?
