Still struggling with this. A further example using a slightly different organisation of the data. The factors "A" and "B" are included in the dataframe in an attempt to get ggplot to generate a legend automatically.
x <- data.frame(value=rnorm(5000, mean=0), case="A") y <- data.frame(value=rnorm(5000, mean=3), case="B") xy <- rbind(x, y) ggplot(xy, aes(x=value, fill=case, group=case)) + geom_histogram(binwidth=0.1) ggplot(xy, aes(x=value, fill=case, group=case)) + geom_density(alpha=0.2) Whilst the legend is generated as expected the histogram and density plots are different. The density plots overlap each other whereas the histogram plots stack. I'm trying the get the histogram plots to overlap, and retain the legend. Is the histogram stacking by design? Can stacking be changed to overlapping? -- View this message in context: http://www.nabble.com/ggplot2-legend-problem-tp25036665p25037500.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
