I'm trying to plot a time series in ggplot, but a date column in my data frame is causing errors. Rather than provide my own data, I'll just refer to the scale_date example at: http://had.co.nz/ggplot2/scale_date.html , which reproduces the error. > df <- data.frame( date = seq(Sys.Date(), len=100, by="1 day")[sample(100, 50)], price = runif(50) ) > dt <- qplot(date, price, data=df, geom="line") + opts(aspect.ratio = 1/4) >...

In page http://had.co.nz/ggplot2/scale_date.html , there is a time series plot for multiple variables at the bottom. i.e qplot(date, value, data = em, geom = "line", group = variable) + + facet_grid(variable ~ ., scale = "free_y") How can I make different color for different series? Thanks -- View this message in...

...sh it a bit further and to a stacked histogram or a multiple line chart. Can anyone suggest a way to go about doing this? I should say, I played around in Hadley Wickham's ggplot package and looked at his website, and there is a way to render multiple lines here: http://had.co.nz/ggplot2/scale_date.html but it was not clear to me how to plot just the dates or an index of the dates as I don't have a value for the y axis, other than the number of times a story was published in that time frame. Regardless, I hope someone can suggest something. Yours, Simon J. Kiss test=sample(1:3, 50,...

I'm having trouble figuring out how to format Date variables when used as axis labels in graphs. The particular case here is an attempt to re-create Nightingale's coxcomb graph with ggplot2, where I'd like the months to be labeled as "Mar 1885", "Apr 1885", using a date format of "%b %Y" applied to label the dates, or really anything other than

Hi I have a timeSeries object (X) with monthly returns. I want to display the returns with a barplot, which I can fix easily. But my problem is labaling the x-axis, if I use the positions from the timeseries It gets very messy. I have tried rotating and changing the font size but it doesn't do the trick. I think the optimal solution for my purpose is too only display every second or third
