I am using the gglikert() function from the ggstats package to create horizontal stacked bar charts centered on the neutral response. I would like to know how to manually set the x-axis limits to 100% on either side of 0%. Here is an example dataframe and code:

example_data <- data.frame(
            Pre = as.factor(c("Somewhat Familiar","Unfamiliar","Somewhat Familiar",
                              "Somewhat Unfamiliar","Somewhat Familiar","Unfamiliar",
                              "Neither Unfamiliar or Familiar","Unfamiliar",
                              "Neither Unfamiliar or Familiar","Unfamiliar")),
           Post = as.factor(c("Very Familiar",
                              "Very Familiar","Somewhat Familiar",
                              "Very Familiar","Very Familiar","Very Familiar",
                              "Very Familiar","Somewhat Familiar","Very Familiar",
                              "Somewhat Familiar"))
   )


gglikert(example_data,
         add_totals = FALSE)

enter image description here

Here, you can see that the function has set the axis limits based on the percentages within each of the groups. I would like the x-axis to go to 100% (as there are other questions with different data distributions and I would like all the axes to be the same, though the answers are slightly different, so I can’t facet them).

I have looked at the documentation for gglikert() and searched Google/Stack overflow, and I do not see an option for the axis limits.

I’ve tried setting the limits with typical ggplot2 approaches (e.g., xlim(0, 100) or xlim (-100, 100), but because the x-axis isn’t on a typical sequential scale like from -100 to 100, these approaches haven’t worked.

I’ve opted for this approach rather than the likert package as it has better functionality for the downstream formatting I want to apply (more control over faceting, facet labels, and bar labels), so would prefer solutions that use gglikert().
