ggplot(data, aes(x, y, col = group)) + # ggplot with legend geom_point()Figure 2: ggplot2 Plot with Legend.As you can see based on Figure 2, we just added a legend to our plot, by moving the col argument within
Figure 1: Two ggplot2 Plots with a Common Legend Using the patchwork Package.As you can see, the previous R code has created a shared legend on the right side of the plot.Example 2: Add Shared Legend to ggplot2 Plots Using gridExtra Package...
inset : % (from 0 to 1) to draw the legend away from x and y axis You can also give the X and Y coordinate of the legend: legend(3, 5, ...) Note that an equivalent page exist concerning legends with ggplot2. # Create data: a=c(1:5) b=c(5,3,4,5,5) c=c(4,5,...

Create a scatter plot: p <- ggplot(df, aes(wt, mpg)) + geom_point(color = 'red') + theme_classic(base_size = 10) Add text labels: # Add text annotations using ggplot2::geom_text p + geom_text(aes(label = rownames(df)), size = 3.5) ...
annotate(): useful for adding small text annotations at a particular location on the plot annotation_custom(): Adds static annotations that are the same in every panel It’s also possible to use the R packageggrepel, which is an extension and providesgeomfor ggplot2 to repeloverlapping textla...

In the next step, we actually draw a bar chart with a backgriund image. To make blackboard.jpg the background image, we need to combine the annotation_custom-function of the ggplot2 package and the rasterGrob-function of the grid package. ggplot(mydata, aes(cut, price, fill = -price...
