我的数据看起来像
language tone count tone_percent label_pos pos
1 c positive 3460 36.16977 18.08488 7
2 c neutral 2046 21.38825 46.86389 7
3 c negative 4060 42.44198 78.77901 7
4 c# positive 3732 41.26949 20.63475 3
5 c# neutral 1832 20.25876 51.39887 3
6 c# negative 3479 38.47175 80.76413 3
7 c++ positive 3136 33.13960 16.56980 8
8 c++ neutral 2008 21.21949 43.74934 8
9 c++ negative 4319 45.64092 77.17954 8
我一直在尝试使用ggplot2条形图来显示它们:
p <-ggplot() + theme_bw() + geom_bar(aes(y=tone_percent, x=reorder(language, -pos), fill=tone), data=data, stat="identity") +
geom_text(data=data, aes(x = language, y = label_pos, ymax=label_pos, hjust = 0.5, label = paste0(round(tone_percent),"%")), size=4) +
labs(x="Language", y="Percentage of tone") +
scale_fill_manual(values=c('#F45E5A', '#5086FF', '#17B12B')) +
theme(legend.position="bottom", legend.direction="horizontal", legend.title = element_blank()) + coord_flip()
但是,图例按字母顺序显示标签,但我想按照与图表中绘制条形图相同的顺序显示它们:正面然后中性然后负面
有没有办法实现这个目标?
