I have created a line chart (plot) in R with labels on each data point. Due to the large number of data points, the plot becomes very fully with labels. I would like to apply the labels only for the last N (say 4) data points. I have tried subset and tail in the geom_label_repel function but was not able to figure them our or got an error message. My data set consist of 99 values, spread over 3 groups (KPI).
I have the following code in R:
library(ggplot) library(ggrepel) data.trend <- read.csv(file=....) plot.line <- ggplot(data=data.trend, aes(x = Version, y = Value, group = KPI, color = KPI)) + geom_line(aes(group = KPI), size = 1) + geom_point(size = 2.5) + # Labels defined here geom_label_repel( aes(Version, Value, fill = factor(KPI), label = sprintf('%0.1f%%', Value)), box.padding = unit(0.35, "lines"), point.padding = unit(0.4, "lines"), segment.color = 'grey50', show.legend = FALSE ) );
I all fairness, I am quite new to R. Maybe I miss something basic.
Thanks in advance.
