Size Classes

Besides dynamic type sizing, sfthemes can also scale all other elements of the plot. This is being done by multiplying all element sizes with a specific multiplier.

class	xSmall	Small	Medium	Large	xLarge	xxLarge	xxxLarge
multiplier	0.75	1	1.25	2	3	4	5

In contrast to ggplot2::ggsave() where you are only able to scale your elements, as mentioned, sfthemes can scale fonts, elements, or both at the same time. Moreover, the re-scaling effect can be previewed as you experiment with your plot.

⚠️ Keep in mind that these values will scale the existing sizes of each elements; therefore, it is recommended that you do not try to scale your entire plot if you are using size or lwd as one of your aes.

Scaling element sizes

By using the element_size_class parameter, we can control the scaling of the elements.

size_class <- "Medium"

gp <- ggplot(iris, aes(x = Sepal.Length, 
                       y = Sepal.Width,
                       color = Species)) +
        geom_point(aes(shape = Species)) + 
        xlab("Sepal Length") + ylab("Sepal Width") +
        labs(title = "SF Light/Dark Theme", 
             subtitle = paste0("Size Class: ", size_class) +
        geom_smooth(method="lm", aes(fill = Species))

# Light
gp + theme_sf_light(element_size_class = size_class) +
        scale_colour_ios_light(accessible = FALSE) +
        scale_fill_ios_light(accessible = FALSE) +
        theme(legend.position = "bottom")

# Dark
gp + theme_sf_dark(element_size_class = size_class) +
        scale_colour_ios_dark(accessible = FALSE) +
        scale_fill_ios_dark(accessible = FALSE) +
        theme(legend.position = "bottom")

Scaling font sizes

By using the font_size_class parameter, we can control the scaling of the fonts.

size_class <- "Medium"

gp <- ggplot(iris, aes(x = Sepal.Length, 
                       y = Sepal.Width,
                       color = Species)) +
        geom_point(aes(shape = Species)) + 
        xlab("Sepal Length") + ylab("Sepal Width") +
        labs(title = "SF Light/Dark Theme", 
             subtitle = paste0("Size Class: ", size_class) +
        geom_smooth(method="lm", aes(fill = Species))

# Light
gp + theme_sf_light(font_size_class = size_class) +
        scale_colour_ios_light(accessible = FALSE) +
        scale_fill_ios_light(accessible = FALSE) +
        theme(legend.position = "bottom")

# Dark
gp + theme_sf_dark(font_size_class = size_class) +
        scale_colour_ios_dark(accessible = FALSE) +
        scale_fill_ios_dark(accessible = FALSE) +
        theme(legend.position = "bottom")

Scaling everything together

By using the size_class parameter, we can control the scaling of both the elements, and fonts.

See readme for the code.
