我正在尝试创建一个条形图,使用ggplot2我在一个变量堆叠并由另一个变量躲避的地方.

这是一个示例数据集:

df=data.frame(
  year=rep(c("2010","2011"),each=4),
  treatment=rep(c("Impact","Control")),
  type=rep(c("Phylum1","Phylum2"),each=2),
  total=sample(1:100,8))

我想创建一个条形图,其中x=treatment,y=total堆叠变量是type,并且躲闪变量是year.当然我可以做其中一个:

ggplot(df,aes(y=total,x=treatment,fill=type))+geom_bar(position="dodge",stat="identity")

ggplot(df,aes(y=total,x=treatment,fill=year))+geom_bar(position="dodge",stat="identity")

但不是两个!感谢任何能提供建议的人.

这是我的代码

    ggplot(df, aes(x=timepoint, y=mean, fill=group)) +
            geom_bar(position=position_dodge(.3), colour="black", stat="identity", width=0.3, , binwidth=0) +
            geom_errorbar(position=position_dodge(.3), width=.25, aes(ymin=mean, ymax=mean+sem)) +
            scale_fill_manual(values=c("#FFFFFF", "#000000"), guide=FALSE) +
            theme_bw() +
            ylab(ylab) +
            xlab("") +
            # xlim("Baseline", "12w") +
            scale_x_discrete(expand = c(0,0), limits=c("Baseline","12w")) + 
            scale_y_continuous(expand = c(0,0) ) + 
            theme(panel.border = element_blank(), panel.grid.major = element_blank(), 
                  panel.grid.minor = element_blank(), axis.line = element_line(colour = "black"))

这是我的输出,我不想要,它在"基线"和"12w"之间的空间太大:

如何去除栏之间的空间？

谢谢

df是这样的:

df <- structure(list(group = c("a1.d.ffa.mean Dysglyc", "a1.c.ffa.mean Control", 
"b1.d.ffa.mean Dysglyc", "b1.c.ffa.mean Control"), timepoint = c("Baseline", 
"Baseline", "12w", "12w"), mean = …
