how to apply aes(size=...) to some sets of data (point) range, for each range seperatly in ggplot2

Question

I have some range of data which I used aes(color=data_range). Now I want to change size in each range when I plot. when I use aes(size=...), all data in all ranges change by size. but how to change size for each specific range? I mean, in each range points grow by their value. But independent of other ranges of data.

Answer 1

One way I think is to add each range in a specific geom_point() and add all of them together. Each geom_point() will have an argument aes(size).
