Difficulty with customizing `ggplot2` themes in R for multi-panel plots using `facet_wrap()`
I've looked through the documentation and I'm still confused about I'm working on a project and hit a roadblock... I've hit a wall trying to I'm trying to customize the theme of a multi-panel plot created with `ggplot2` using `facet_wrap()`... Specifically, I want to change the background color and text size for each panel. I've defined a custom theme, but the changes don't seem to apply correctly to the individual facets, and instead, only the last facet reflects the theme adjustments. Here's a snippet of my code: ```R library(ggplot2) # Sample dataset data(mtcars) # Custom theme function my_custom_theme <- function() { theme_minimal() + theme(panel.background = element_rect(fill = 'lightblue'), text = element_text(size = 12)) } # Creating the plot p <- ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point() + facet_wrap(~ cyl) + my_custom_theme() print(p) ``` When I run this code, the background color is applied, but it only appears in the last facet. The text size seems to be ignored for all facets. I've tried adding `theme()` directly within the `facet_wrap()`, but it didn't help either. I also checked the version of `ggplot2` Iām using, which is 3.3.5. Is there a limitation or a specific way to apply themes correctly across all facets? Any insights on how I can achieve a consistent appearance across all panels would be appreciated! The project is a web app built with R. I'm working in a Ubuntu 22.04 environment. What's the best practice here? This is my first time working with R 3.11. Thanks for taking the time to read this! What's the best practice here?
