执行日志坐标转换时ggplot道奇栏不显示

Question

我在使用带有log10比例的坐标转换时遇到ggplot问题。我希望在log10轴上绘制数据，但不缩放数据本身。这与sqrt一起使用，但是当使用日志轴坐标时，不会出现任何条形。请你告诉我我错过了什么？

d <- data.frame(x=factor(c(1,1,2,2)), y=c(1,2,3,4), fill=factor(c(1,2,3,4))) 

#sqrt axis tranformaion works
ggplot(d, aes(x = x, fill = fill)) +
  geom_bar(aes(y = y), stat = "identity", position = "dodge") +
  coord_trans(y = "sqrt")

#log10 axis tranformaion doesn't work
ggplot(d, aes(x = x, fill = fill)) +
  geom_bar(aes(y = y), stat = "identity", position = "dodge") +
  coord_trans(y = "log10")

#log10 axis tranformaion works with points rather than bars
ggplot(d, aes(x = x, fill = fill)) +
  geom_point(aes(y = y), stat = "identity") +
  coord_trans(y = "log10")

Answer 1

尝试使用scale_y_log10功能：

ggplot(d, aes(x = x, fill = fill)) +
  geom_bar(aes(y = y), stat = "identity", position = "dodge") +
  scale_y_log10()
