我有一张看起来像这样的桌子。

structure(c(13704L, 14059L, 14263L, 14450L, 14057L, 15503L, 14230L,

14594L, 14702L, 13891L, 12891L, 12939L), .Dim = c(7L, 10L), .Dimnames = structure(list( …ggmap(location) +
geom_density_2d(aes(long, lat), df) +
geom_point(aes(long, lat,**color = special**),alpha = 0.5,data = df)
当我将颜色更改为填充时,我看不出有什么不同,例如:
ggmap(location) +
geom_density_2d(aes(long, lat), df) +
geom_point(aes(long, lat,**fill = special**),alpha = 0.5,data = df)
这两个论点之间的主要区别是什么？
