I have median household income income data for my locality by block group. I was trying to figure out the best way to symbolize this data and came across a fantastic ESRI blog:
In Figure 4 the author presents a map of the same data for DC where standard deviation classification is used to make the data more meaningful. He states that "This example anchors the map using the US median household income of $46,533." How does one anchor data to a specific figure? I think the example illustrated in the blog is a fantastic way to show my data, but I am unsure how to specify an anchor. The software automatically calculates the mean and the deviation is based on that. Can anyone help with this? Thanks so much!
