# Scales | |
## color | |
Take your scatterplot that you just made and add a scale using `scale_color_brewer`. Take a look at the help docs and choose a palette other than the default (hint: look at the `palette` argument). | |
```{r} | |
ggplot(data = nhanes, | |
mapping = aes(x = weight, | |
y = height, | |
color = phys_active)) + | |
geom_point() + | |
scale_color_brewer(palette = "Dark2") | |
``` | |
Do nearly the same thing to change the color of the last bar chart you made (the one about sleep and gender). | |
```{r} | |
ggplot(data = sleep_by_gender, | |
mapping = aes(x = gender, | |
y = avg_sleep, | |
fill = gender)) + | |
geom_col() + | |
scale_fill_brewer(palette = "Dark2") | |
``` | |
## x and y axes | |
Copy the graph you just made and change the y axis so it goes from 0 to 8. | |
```{r} | |
ggplot(data = sleep_by_gender, | |
mapping = aes(x = gender, | |
y = avg_sleep, | |
fill = gender)) + | |
geom_col() + | |
scale_fill_brewer(palette = "Dark2") + | |
scale_y_continuous(limits = c(0, 8)) | |
``` | |
Copy the last code chunk. Then adjust the breaks on the y axis so that it shows 0 to 8 by 1 (i.e. 0, 1, 2, etc). | |
```{r} | |
ggplot(data = sleep_by_gender, | |
mapping = aes(x = gender, | |
y = avg_sleep, | |
fill = gender)) + | |
geom_col() + | |
scale_fill_brewer(palette = "Dark2") + | |
scale_y_continuous(limits = c(0, 8), | |
breaks = c(0, 1, 2, 3, 4, 5, 6, 7, 8)) | |
``` |
