Hi all, I have a question about setting arbitrary breaks/labels when using GGPLOT and date/time data on the x-axis. I want to specify the breaks/limits arbitrarily rather than using scale_x_date(major = 'blah'), much like when arbitrarily defining breaks/labels using scale_x_discrete(breaks = blah, labels = blah) I have tried variants such as: scale_x_date(major = seq(from = as.Date('2000-01-01'), to = as.Date('2009-01-01'), by = 'months')); etc but c...

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

Hi, I would like to customise my date series on the plot. I tried this: dt_ts <- ts(dt) autoplot(dt_ts[,2]) + ylab("Charge counts") + xlab("Daily") but the label is not the date series. Tqvm for any help given. > dput(dt) structure(list(time = c("1/1/2014", "2/1/2014", "3/1/2014", "4/1/2014", "5/1/2014",

All: I am using the command: qplot(date,MAE,data=data,facets=INTERVAL~type) which works fine except that the dates for my date axes are crunched together so much that they are unreadable. I can not find an option that I can set that will automatically reduce the x-axis labels to fit the available space. regards to all? -- Thomas E Adams National Weather Service Ohio River Forecast Center

Hola, Estoy haciendo unas gráficas de evolución temporal con el paquete "ggplot" y me he encontrado con una dificultad que no logro resolver. En el eje "x" tengo las fechas y en el "y" la concentración de un parámetro. En el eje x me sale de forma predeterminada intervalos en años (de 2012 a 2016), y unicamente salen 3 etiquetas (una cada 2 años). Necesito

Hi, I have this script: dat <- data.frame(X = halistat$Date,Y1 = halistat$avg,Y2 = halistat$stdev) ggplot(data = dat, aes(x = X, y = Y1, ymin = Y1 - Y2, ymax = Y1 + Y2)) + geom_point() + # points at the means geom_line() + # if you want lines between pints geom_errorbar() # error bars, Y1 - Y2 and Y1 + Y2 halistat$Date values: 29/1/10 21/2/10 30/3/10 30/4/10 30/5/10 In the resulted

Use 'binwidth = x' to adjust this. OK, I tried formatting Date first, in different ways. Each time, I get a graphical result, but I don't know how to use format() for dates to make t...

Hello! If you run the whole code below, it'll produce a stacked diagram. And it looks good - because the tick-marks are aligned with the grid. However, if I stretch the graph window, grid becomes misaligned with the tickmarks. Or, rather, it seems aligned for the first and the last tick mark, but not for tickmarks in between. Can it be addressed? Thank you! Dimitri ### Creating a data set
