I mapping the number of Boko Haram victims in each state of Nigeria for several years. I chose to make a proportional symbol maps using the centroid of each state. For a given year, the area of the circular symbol is directly related to the number of deaths.
Using ArcMap's proportional symbols symbology does the job, but I have a problem with the legend:
The default legend offers me 3 categories which are not very convenient (1, 100, 10.000). I would like to be able to change the breaks in the legend to, say, 100, 1.000, 5.000, 10.000.
Is there a way to do this?
