我的数据:
df <- data.frame(sp = c(LETTERS[1:8]),
tr = c("NS", "LS", "NS", "LS", "LS", "HS", "HS", "HS"),
bv = c(14, 5, 11, 5.6, 21, 5.4, 2, 4.8),
av = c(0.0, 14, 21, 48.4, 15, 55.6, 37, 66.2))
我做条形图
library(reshape2)
df1 <- melt(df, id.vars = c("sp", "tr"))
ggplot(aes(sp, value, fill = variable) , data = df1) + theme_classic() +
geom_bar(aes(lty = tr), lwd = 1.2, data = df1, stat = "identity", colour = "black", width =.8) +
theme(legend.position = "bottom" ) +
scale_linetype_discrete(name = "ja")
输出
我不喜欢的是传说。我想从第二部分&#34; ja
&#34;中选择线条类型。并删除&#34; variable
&#34;部分。我希望在图例框中有白色背景,而不是灰色背景。
