Description
@mtennekes -- would you be able to let me know what is the scope and limitations of the extra.ggplot2 argument in the charts functions? For example, I've tried to use the dark theme, and the whole chart is not longer readable. Thus:
- What is the scope of this argument?
- Is it possible to specify a few ggplot2 options with it?
library(tmap)
library(spData)
tm_shape(nz) +
tm_polygons("Median_income",
fill.chart = tm_chart_histogram())
tm_shape(nz) +
tm_polygons("Median_income",
fill.chart = tm_chart_histogram(
extra.ggplot2 = ggplot2::theme_dark()
))

Start with the charts functions and the extra.ggplot2 argument shown in the tm_chart_histogram examples. Trace how supplied ggplot2 options are applied, then document the argument's scope, supported options, and the limitation demonstrated by theme_dark().
