Color aesthetic mapping #47

Open AWinterman opened 12 years ago

AWinterman commented 12 years ago

The user should be able to map a variable to the color of each shape on the graph. In ggplot, this would run:

require(ggplot2)
df = data.frame(x=rnorm(100), y=rnorm(100, 10, 1), color=rep(1:4, 25))
ggplot(data = df)+geom_point(aes(x = x, y= y, color=color))

It seems like a simple enough fix for geom_point at least. Is there a reason why this hasn't been done?

Hi! Sorry for not getting back to you. The reason nothing's been done is that we stopped developing this code about 6 or 7 months ago. However, I'm trying to start getting back into this code so we can get a nice working d3py out there so that others can find it useful or beat it with more awesome implementations.

As for the colour aesthetic, it's a good idea! There's no good reason it hasn't been done. I'll keep this issue open. Please do feel free to have a go at implementing it. The necessary bits and bobs would live in
