annotate marks in chart ggplot

Question

How to change the labels of marks in scatter chart?I tried to change the size of marks and labels,but still the marks are overlapping.

Is there any way out to this problem?

Answer 1

One way is to use ggrepel package. It provides a function called geom_text_repel() that smartly provides a way to show labels to each point in a chart.

The syntax of geom_text_repel() is the same as that of geom_text().

ggplot(mapping) + geom_*() + geom_text_repel(mapping,label = "")

Hope it helps you!
