add_xy_position continuous x axis

[jyuen531]

Hi! I'm wondering if there's a solution to getting the positioning correct for a continuous x axis. Here's an example of the problem when I specify "numeric.x.axis = T"

lp <- ggline(
ToothGrowth, x = "dose", y = "len", add = "mean_sd",
color = "supp", palette = c("#00AFBB", "#E7B800"), numeric.x.axis = T
)
stat.test <- ToothGrowth %>%
group_by(dose) %>%
t_test(len ~ supp) %>%
adjust_pvalue(method = "bonferroni") %>%
add_significance("p.adj")
stat.test
stat.test <- stat.test %>%
add_xy_position(fun = "mean_sd", x = "dose")
lp + stat_pvalue_manual(
stat.test, label = "p.adj.signif",
linetype = "blank", vjust = 2
)

Thank you!
