具有这样的数据框:
从像这样的数据框中:
data <- data.frame(year = c(2010,2011,2012,2010,2011,2012),
name = c("stock1","stock1","stock1","stock2","stock2","stock2"),
value = c(0,3,1,4,1,3))
我想创建一个情节,我用这个:
library(ggplot2)
ggplot(data=data, xName="year", groupName="name", brewerPalette="Blues")
但是我无法收到剧情。电话有问题吗?

如果您希望对条形图进行分组(如我从您的代码中猜到的那样),则此代码可能会有所帮助:
ggplot(data = data, aes(x = as.factor(year), y = value, fill = name)) +
geom_bar(stat = "identity", position = position_dodge(0.8), width = 0.7) +
scale_fill_brewer(palette = "Blues")

我认为您需要这样的东西:
library(ggplot2)
library(dplyr)
library(RColorBrewer)
df %>%
group_by(name) %>%
ggplot(aes(year,value,fill=name))+
geom_col()+
scale_fill_brewer(palette = "Blues")
