Request for easy way to label tiles

[kamilsi]

Mosaic plots are great way to inform about proportions within groups, but they give you now way to indicate the total sample size / subgroup sizes. It's impossible to use geom_mosaic with geom_text to label tiles. Would it be possible to create an easy way to add geom_text to plots with geom_mosaic? That could result in:

1. labeling tiles (like here)
2. presenting raw numbers behind plots (which is crucial in case you are visualizing populations of different sizes).

I second the motion! It would be extremely helpful to be able to label the tiles in an easy way.

I believe geom_mosaic_labeldoes that.

Quick hack if you want to display the count of cases:

ggplot(data = titanic) +
  ggmosaic::geom_mosaic(aes(x = ggmosaic::product(Class), fill = Survived)) +
  ggmosaic::geom_mosaic_label(aes(x = ggmosaic::product(Class), fill = Survived, label = after_stat(.wt))) +
  ggmosaic::scale_x_productlist()

This reply is very helpful. I kept searching for a long time until I found this.
For new readers, just note that the function name now is ggmosaic::geom_mosaic_text()
