# How to Order Y-Axis Labels Alphabetically in ggplot2

You can use the following basic syntax to order the y-axis labels alphabetically in ggplot2:

```#sort y-axis variable in alphabetical order
df\$y_var<- factor(df\$y_var, levels=rev(sort(df\$y_var)))

#create scatter plot with y-axis in alphabetical order
ggplot(df, aes(x=x_var, y=y_var)) +
geom_point()
```

The following example shows how to use this syntax in practice.

## Example: Order Y-Axis Labels Alphabetically in ggplot2

Suppose we have the following data frame in R that shows the points scored by various basketball teams:

```#create data frame
df <- data.frame(team=c('B', 'D', 'E', 'F', 'A', 'C', 'H', 'G'),
points=c(22, 12, 10, 30, 12, 17, 28, 23))

#view data frame
df

team points
1    B     22
2    D     12
3    E     10
4    F     30
5    A     12
6    C     17
7    H     28
8    G     23
```

If we create a scatter plot with points on the x-axis and team on the y-axis, ggplot2 will automatically display the teams in alphabetical order (starting from the bottom):

```library(ggplot2)

#create scatter plot
ggplot(df, aes(x=points, y=team)) +
geom_point(size=2)```

Notice that the labels on the y-axis are in alphabetical order from A to Z, starting from the bottom.

To arrange the y-axis labels in reverse alphabetical order, we can use the following code:

```library(ggplot2)

#sort y-axis variable in alphabetical order
df\$team<- factor(df\$team, levels=rev(sort(df\$team)))

#create scatter plot with y-axis in alphabetical order
ggplot(df, aes(x=points, y=team)) +
geom_point()```

Notice that the labels on the y-axis are now in reverse alphabetical order, starting from the bottom.
