I think it is an efficient of proceeding: I first select the finest gap between two ticks (here 0.1) and create the sequence with seq(), then create the main set of tick marks and finally use setdiff() will to add the remaining tick marks. # You can also create your own and supply them to the trans argument. As you may have noticed, I use setdiff() to select the complementary set of ticks. # There are a few built in transformation that you can use: m + scale_y_log10() ![]() #Ggplot rename x ticks how to#M + scale_x_continuous(breaks= c ( 2, 5, 8 ), labels= expression (Alpha, Beta, Omega)) How to change x-axis tick label names, order and boxplot colour using R ggplot I have a folder containing csv files, each with two columns of data e.g. M + scale_x_continuous(breaks= c ( 2, 5, 8 ), labels= c ( "horrible", "ok", "awesome" )) Its somehow amazing to me that the option for slanted or rotated axes labels is not an option within the basic plot () or axis () functions in R. ![]() # * manually label the ticks m + scale_x_continuous(breaks= c ( 2, 5, 8 ), labels= c ( "two", "five", "eight" )) You can make the x axis values into a factor and set the order of its levels. M + scale_x_continuous(breaks= c ( 1, 3, 7, 9 )) I have created a tile plot, as below: Id like to rename the y axis ticks, instead of 1 - to 'country', 2- to 'city', 3 - to 'all'. # * choose where the ticks appear m + scale_x_continuous(breaks= 1 : 10 ) # you can also use the short hand functions xlim and ylim m + ylim( 0, 5000 ) M + scale_x_continuous(limits= c ( 7, 8 )) # * modify the axis limits m + scale_y_continuous(limits= c ( 0, 5000 )) M + scale_y_continuous( expression (votes^alpha)) In this case, we utilize scalexdiscrete to modify x axis tick labels for ggplot objects. Use scalexdiscrete to Modify ggplot X Axis Tick Labels in R scalexdiscrete together with scaleydiscrete are used for advanced manipulation of plot scale labels and limits. Syntax: ggplot (data , mapping aes ()) + () The data can be binded into the scatter plot using the data attribute of the ggplot method. This article will introduce how to modify ggplot x-axis tick labels in R.In another post I read the advice to use xaxt="n", but I cannot get that to work with ggplot2.# Manipulating the default position scales lets you: # * change the axis labels m + scale_y_continuous( "number of votes" ) The ggplot () method can be used in this package in order to simulate graph customizations and induce flexibility in graph plotting. I also tried levels=c(1,2,3,4,5) and labels=c("1 hour", "4 hours", etc) butĪll I get is an empty x-axis, no new labels. I searched this site and google and came up with this code: plot1 <- plot + scale_x_discrete(labels=c("1"="1 hour", "2"="4 hours", "3"="8 hours", "4"="POD1 Morning", "5"="POD1 Afternoon")) I would like to replace 1, 2, 3, 4, 5 on the x-axis with the labels 1 hour, 4 hours, 8 hours, POD1 Morning and POD1 Afternoon. With several commands, I adjusted the graph to my liking and I have this: Set xaxt n and yaxt n to remove the tick labels of the plot and add the new labels with the axis function. I am quite new to R and I am trying to create a spaghetti plot to compare in 4 groups the percentage of patients taking rescue medication, at different timepoints (1 hour after surgery, 4 hours, 8 hours and post-operative day 1 morning and post-operative day 1 afternoon).Īfter playing around, I created a decent graph, starting from this code: plot <- ggplot(data=rescue, aes(Measurement, Percentage, color=factor(Group))) + geom_line() ![]()
