Решетка Barchart: управление разделением элементов в легенде

Question

Пожалуйста, рассмотрите короткий код в конце поста. Он генерирует диаграмму, где все так, как я хочу, за исключением некоторой незначительной настройки легенды. Я могу контролировать интервал между текстом в двух строках легенды, но как я могу принудительно разделить красный и синий прямоугольники в легенде? Любое предложение приветствуется.

Answer 1

Просто установите height = <something less than 1>, как это:

barchart(
  number ~ country ,
  groups = as.factor(year),
  data = df_tot,
  origin = 0,
  aspect = "fill",
  par.settings = c(ggplot2like(col = c("blue", "red"))),
  axis = axis.grid,
  xlab = list("Number of Beneficiaries", cex = 1.2),
  ylab = list("Country", cex = 1.2),
  main = list(NULL),
  between = list(x = 1),
  scales = list(cex = 1),
  auto.key = list(
      title = "Year",
      height = 0.8,
      columns = 1,
      space = "right",
      padding.text = 3
    )
)
