# Discrete and Continuous Fill Scale Using generate_colors
|
|
|
|
Drop-in replacement for
|
|
[`viridis::scale_fill_viridis()`](https://sjmgarnier.github.io/viridis/reference/scale_viridis.html)
|
|
that works with any palette supported by
|
|
[`generate_colors()`](https://agdamsbo.github.io/FreesearchR/reference/generate_colors.md).
|
|
|
|
## Usage
|
|
|
|
``` r
|
|
scale_fill_generate(palette = "viridis", discrete = TRUE, ...)
|
|
|
|
scale_color_generate(palette = "viridis", discrete = TRUE, ...)
|
|
```
|
|
|
|
## Arguments
|
|
|
|
- palette:
|
|
|
|
Passed to
|
|
[`generate_colors()`](https://agdamsbo.github.io/FreesearchR/reference/generate_colors.md).
|
|
Either a palette name string or a function.
|
|
|
|
- discrete:
|
|
|
|
`logical`. If `TRUE` (default), a discrete scale is returned. If
|
|
`FALSE`, a continuous scale is returned.
|
|
|
|
- ...:
|
|
|
|
Additional arguments passed to
|
|
[`ggplot2::scale_fill_manual()`](https://ggplot2.tidyverse.org/reference/scale_manual.html)
|
|
(discrete) or
|
|
[`ggplot2::scale_fill_gradientn()`](https://ggplot2.tidyverse.org/reference/scale_gradient.html)
|
|
(continuous).

## Examples
|
|
|
|
``` r
|
|
library(ggplot2)
|
|
|
|
# Discrete
|
|
ggplot(mtcars, aes(x = wt, y = mpg, fill = factor(cyl))) +
|
|
geom_col() +
|
|
scale_fill_generate(palette = "Set1")
|
|
|
|
|
|
# Continuous
|
|
ggplot(mtcars, aes(x = wt, y = mpg, fill = mpg)) +
|
|
geom_point(shape = 21, size = 3) +
|
|
scale_fill_generate(palette = "viridis", discrete = FALSE)
|
|
|
|
|
|
ggplot(mtcars, aes(x = wt, y = mpg, color = factor(cyl))) +
|
|
geom_point() +
|
|
scale_color_generate(palette = "Set1")
|
|
```
