geom_path question

[Peter Flom]

Hello again

From the examples for geom_path

I run

myear <- do.call(rbind, by(movies, movies$year, function(df) data.frame(year=df$year[1], mean.length = mean(df$length), mean.rating=mean(df$rating))))
p <- ggplot(myear, aes(x=mean.length, y=mean.rating))
p + geom_path()

# Add aesthetic mappings
p + geom_path(aes(size=year))

but, in the resulting plot, the line width is constant

If I run the next line

p + geom_path(aes(colour=year))

the color does vary, but several of the colors are almost invisible, and the ones that are visible are nearly impossible to distinguish from each other.

Help, please?

Peter

Hi Peter,

Both problems are fixed in the development version. I'm hoping to get
another release out in the next couple of weeks.
