[R] ggplot2 bar chart: order display for each group

[Kai Yang]

Hello List,
I submitted the code below, it will show two groups of avg_time bar chart for each gc_label and got the plot.

ggplot(s8_GCtime, aes(fill=GTresult, y=avg_time, x=gc_label, label = avg_time)) + 
  geom_bar(position=position_dodge(), stat="identity") +
  geom_text(aes(label=avg_time), vjust=1.6, position = position_dodge(0.9), size=3.5)+
  theme(axis.text.x = element_text(angle = 45))



I found the ggplot put all of small number of avg_time on left side, bigger number of avg_time on right side for each gc_label. But I hope to use order by GTresult (see the plot I attached, I want to put all of blue in right and orange in left side, but Amber and Nadyah are not in that order). Could you tell me how to do this?

Thanks,
Kai
