我有一个数据集，如下所示。我想在x轴上有物种，在y轴上计数。对于每个物种，我想有一个单独的酒吧年。所以有些物种被计算了所有四年，并希望在x轴上看到4个不同颜色的酒吧。
我的尝试：

ggplot(data = data, aes(x = species_capture, y = count, fill = year)) +
  geom_col(position = "dodge2")

数据：

data <-
  structure(
    list(
      year = c(
        2020,
        2020,

一种方法是创建一个复合列和图表：

data$species_capture_year = paste0(data$species_capture,"-",data$year)

ggplot(data = data, aes(x = species_capture_year, y = count, fill = factor(year))) +
   geom_col(position = "dodge2")+
   theme(axis.text.x = element_text(angle = 45, hjust = 1))

另一种是将情节分面化：

ggplot(data = data, aes(x = year, y = count, fill = factor(year))) +
   geom_col(position = "dodge2")+
   theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
   facet_wrap(vars(species_capture))

考虑到y轴计数的广泛可变性，您还可以修改上述内容以允许y轴的自适应缩放：

ggplot(data = data, aes(x = year, y = count, fill = factor(year))) +
   geom_col(position = "dodge2")+
   theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
   facet_wrap(vars(species_capture), scales = "free_y")

尝试将年份设置为一个因子，而不是连续的。（为了可读性，我也旋转了x轴标签。）

ggplot(data = data, aes(x = species_capture, y = count, fill = as.factor(year))) +
  geom_col(position = "dodge2") + 
  theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))
