In another post I read the advice to use xaxt="n", but I cannot get that to work with ggplot2. 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. Syntax: ggplot (data , mapping aes ()) () The data can be binded into the scatter plot using the data attribute of the ggplot method.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")) The ggplot () method can be used in this package in order to simulate graph customizations and induce flexibility in graph plotting. 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: OâReilly Media.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() Help on all the ggplot functions can be found at the The master ggplot help site.Ī useful cheat sheet on commonly used functions can be downloaded here.Ĭhang, W (2012) R Graphics cookbook. To further customise the aesthetics of the graph, including colour and formatting, see our other ggplot help pages: Use the second argument of xticks to set the labels: import numpy as np import matplotlib.pyplot as plt data np.random. Print(IrisPlot myblanktheme labs(title = "Petal and sepal \nlength of iris", y = "Petal length (cm)", x = "Sepal length (cm)")) Legend.text = element_text(face = "italic", colour = "steelblue4", family = "Helvetica"),Īxis.title = element_text(family = "Helvetica", size = (10), colour = "steelblue4"), Plot.title = element_text(family = "Helvetica", face = "bold", size = (15)), The following code would remove the legend title and axis text. To do this you use the code = element_blank(), remembering those open and closed brackets. For example, size = (3).Īnother option is to remove the text from the plot entirely. Remember to include ââ before and after the colour name. the colour can be changed to any of the colours listed here. the type of emphasis, with options including bold, italic and âalicâ. Examples of fonts include: âPalatinoâ, âHelveticaâ, âCourierâ, âTimesâ. To alter the labels on the axis, add the code labs(y y axis name, x x axis name) to your line of basic ggplot code. The font, colour, size and emphasis of any of these labels can be altered by arguments within element_text(your format).
