How to Add Labels Directly in ggplot2 in R - GeeksforGeeks To put labels directly in the ggplot2 plot we add data related to the label in the data frame. Then we use functions geom_text () or geom_label () to create label beside every data point. Both the functions work the same with the only difference being in appearance. The geom_label () is a bit more customizable than geom_text (). Legends in ggplot2 [Add, Change Title, Labels and Position ... - R CHARTS # install.packages ("ggplot2") library(ggplot2) ggplot(df, aes(x = x, fill = group)) + geom_density(alpha = 0.5) + scale_fill_hue(labels = c("G1", "G2")) Reorder the labels In case you want to reorder the labels of the legend you will need to reorder the factor variable. In this example we have created a new variable with the new order.

Chapter 4 Labels | Data Visualization with ggplot2 4.6 Axis Range. In certain scenarios, you may want to modify the range of the axis. In ggplot2, we can achieve this using: xlim() ylim() expand_limits() xlim() and ylim() take a numeric vector of length 2 as input expand_limits() takes two numeric vectors (each of length 2), one for each axis in all of the above functions, the first element represents the lower limit and the second element ...

How to Label Points on a Scatterplot in R (With Examples) This tutorial provides an example of how to label the points on a scatterplot in both base R and ggplot2. Example 1: Label Scatterplot Points in Base R. To add labels to scatterplot points in base R you can use the text() function, which uses the following syntax: text(x, y, labels, …) x: The x-coordinate of the labels; y: The y-coordinate of ... How to Add Labels to Select Points with ggrepel? In this post, we will see how to add labels or annotations to select data points such that the labels don't overlap with each other. We will use the R package ggrepel together with ggplot to add labels without overlaps. More specifically we will use geom_text_repel() function from ggrepel to add annotations to data points. Add text labels with ggplot2 - The R Graph Gallery # library library (ggplot2) # Keep 30 first rows in the mtcars natively available dataset data= head (mtcars, 30) # 1/ add text with geom_text, use nudge to nudge the text ggplot (data, aes ( x= wt, y= mpg)) + geom_point () + # Show dots geom_text ( label=rownames (data), nudge_x = 0.25, nudge_y = 0.25, check_overlap = T ) 8 Annotations | ggplot2 label <- data.frame ( waiting = c (55, 80), eruptions = c (2, 4.3), label = c ("peak one", "peak two") ) ggplot (faithfuld, aes (waiting, eruptions)) + geom_tile ( aes (fill = density)) + geom_label (data = label, aes (label = label)) Labelling data well poses some challenges: Text does not affect the limits of the plot.

Labeling contour lines in R with ggplot2, metR and isoband With labels on each contour, it's trivial to know the height of each point without having to mentally map colours to numbers. It would be great being able to do this with ggplot2. One possibility is to use the old metR::geom_text_contour() function. GGPlot Axis Labels: Improve Your Graphs in 2 Minutes - Datanovia This article describes how to change ggplot axis labels (or axis title ). This can be done easily using the R function labs () or the functions xlab () and ylab (). Remove the x and y axis labels to create a graph with no axis labels. For example to hide x axis labels, use this R code: p + theme (axis.title.x = element_blank ()). Text — geom_label • ggplot2 To add labels at specified points use annotate () with annotate (geom = "text", ...) or annotate (geom = "label", ...). To automatically position non-overlapping text labels see the ggrepel package. Aesthetics geom_text () understands the following aesthetics (required aesthetics are in bold): x y label alpha angle colour family fontface group geom_label function - RDocumentation Description. Text geoms are useful for labeling plots. They can be used by themselves as scatterplots or in combination with other geoms, for example, for labeling points or for annotating the height of bars. geom_text () adds only text to the plot. geom_label () draws a rectangle behind the text, making it easier to read.

Point labels perpendicular to a curve in ggplot2 - GitHub Pages Summary How to place legible labels for points on a curve in ggplot2 I would like to label points on a sine function so that the labels are always legible. In a sine wave plot in which θ θ ranges from 0 to 2 π π, sin(θ) sin ( θ) ranges from −1 to +1. Thus, the plot's xy ratio is plot ratio = 2π − 0 1 − (−1) = π plot ratio = 2 π − 0 1 − ( − 1) = π

Points — geom_point • ggplot2 The point geom is used to create scatterplots. The scatterplot is most useful for displaying the relationship between two continuous variables. It can be used to compare one continuous and one categorical variable, or two categorical variables, but a variation like geom_jitter(), geom_count(), or geom_bin2d() is usually more appropriate.
