Remove 'A' from Legend When Using Aesthetics and Geom_Text

Remove 'a' from legend when using aesthetics and geom_text

Set show.legend = FALSE in geom_text:

ggplot(data = iris,
       aes(x = Sepal.Length, y = Sepal.Width, colour = Species,
           shape = Species, label = Species)) + 
    geom_point() +
    geom_text(show.legend = FALSE)

The argument show_guide changed name to show.legend in ggplot2 2.0.0 (see release news).

Pre-ggplot2 2.0.0:

With show_guide = FALSE like so...

ggplot(data = iris, aes(x = Sepal.Length, y = Sepal.Width , colour = Species,
                        shape = Species, label = Species ), size = 20) + 
geom_point() +
geom_text(show_guide  = FALSE)

You can use show.legend = FALSE to exclude the a symbol from your example:

geom_text_repel(aes(SI, EI), show.legend = FALSE)

How to hide legend for geom_label only in ggplot?

geom_label(..., show.legend = FALSE) +

show.legend = FALSE overriden by geom_text

I would remove the legends with ggplot2::guides(fill=FALSE, color=FALSE). Also I would put your ggplot2::theme to the last line, otherwise ggplot2::theme_minimal() could overwrite some of your adjustments

Remove legend in ggplot

I couldn't run your code, but I rebuilt it with iris.

Like Matt suggested, one thing would be, remove fill=F:

ggplot(data=iris, aes(x = SepalLength , y = PetalLength, group=Name)) +
  geom_point() +
  geom_line() +
  stat_smooth(method = "loess",se = T, aes(color=Name)) +
  geom_ribbon(aes(ymin = 1, ymax = 3),alpha = 1/5) +
  scale_x_continuous(breaks = 0:2, labels = c(0, 6, 12)) 

Or if you need it for some reason, use guides(fill="none"):

ggplot(data=iris, aes(x = SepalLength , y = PetalLength, group=Name)) +
  geom_point() +
  geom_line() +
  stat_smooth(method = "loess",se = T, aes(color=Name)) +
  geom_ribbon(aes(ymin = 1, ymax = 3, fill=FALSE),alpha = 1/5) +
  scale_x_continuous(breaks = 0:2, labels = c(0, 6, 12)) +
  guides(fill="none")

Output:

Why adding geom_text to ggplot changes the legend line type?

As far as I understand, ggplot creates a legend for each geom_... Therefore these little (and at times annoying) "a"s appear. There are several options to hide a legend. Adding show.legend = FALSE in the geom_-call is probably most straightforward:

 ...
geom_text(aes(...label = round(mean_health, 0)),..., show.legend = FALSE)
...
