[英]Control Discrete Tick Labels in ggplot2 (scale_x_discrete)
[英]Changing x-axis tick labels ggplot2 not working, making axis disappear, scale_x_discrete
我正在嘗試更改ggplot中的x軸刻度標簽,但由於某種原因我無法使其工作。 我有以下代碼和情節:
ggplot(over36mo, aes(x=raceeth,y=pt,fill=factor(year.2cat))) +
geom_bar(stat="identity",position="dodge") +
geom_errorbar(aes(ymax=pt+se, ymin=pt-se), width=0.2, position=position_dodge(0.9)) +
scale_fill_discrete(guide=FALSE) +
scale_y_continuous(breaks=seq(0, 0.26, 0.02), limits=c(0,0.26)) +
labels=c("NHW","NHB","NHNA/PI","NHA","H")) +
theme(axis.line.x=element_line(color="black"),
axis.line.y=element_line(color="black"),
panel.background=element_blank(),
panel.border=element_blank(),
panel.grid.major=element_blank(),
panel.grid.minor=element_blank(),
plot.background=element_blank()) +
xlab("All ages") + ylab("")
但是當我嘗試用scale_x_discrete
將scale_x_discrete
為不同的標簽時,x軸會像這樣消失:
ggplot(over36mo, aes(x=raceeth,y=pt,fill=factor(year.2cat))) +
geom_bar(stat="identity",position="dodge") +
geom_errorbar(aes(ymax=pt+se, ymin=pt-se), width=0.2, position=position_dodge(0.9)) +
scale_fill_discrete(guide=FALSE) +
scale_y_continuous(breaks=seq(0, 0.26, 0.02), limits=c(0,0.26)) +
labels=c("NHW","NHB","NHNA/PI","NHA","H")) +
theme(axis.line.x=element_line(color="black"),
axis.line.y=element_line(color="black"),
panel.background=element_blank(),
panel.border=element_blank(),
panel.grid.major=element_blank(),
panel.grid.minor=element_blank(),
plot.background=element_blank()) +
xlab("All ages") + ylab("") +
scale_x_discrete(breaks=c("1","2","3","4","5"), labels=c("NHW","NHB","NHNA/PI","NHA","H")) +
這可能是顯而易見的,但我無法弄明白。 如果有人想試一試,這是我的數據的輸入!

這是因為您正在設置離散x
刻度,但您的x
值是數字。 如果要將它們視為離散,請轉換為因子。 只需將第一部分更改為
ggplot(over36mo, aes(x=factor(raceeth), y=pt, fill=factor(year.2cat)))
它應該工作得很好。
