当我使用barplot
时,如果名称太大,我看不到栏的名称。例如:
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Barplot",
names.arg=c("This is bar 1...1", "This is bar 1...2",
"This is bar 1...3", "This is bar 1...4"),
xpd=TRUE, las=1, lwd=1, cex.names=0.5)
当我使用horiz=TRUE
时,我看不到左边的名字:
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Barplot",
names.arg=c("This is \nbar 2...1", "This is bar 2...2",
"This is bar 2...3", "This is bar 2...4"),
xpd=TRUE, las=1, lwd=1, horiz=TRUE, space=1)
在名称中使用换行符(例如“This is \ nbar 2 ... 1”)或减少文本大小,例如cex.names=0.5
“解决”问题但我更愿意添加空格以便名字合适。
是否有能力改变整个人物的宽度,包括情节?

当horiz=FALSE
(默认值)时,一个选项是使用las=2
绘制垂直于x轴的条形名称,并将高度添加到底部边距以适应名称的长度。要向边距添加空格,请使用par(mar=c(b, l, t, r))
,其中b
,l
,t
和r
是数字,给出宽度/高度的行数你想要分别是底部,左边,上边和右边距。
例如:
par(mar=c(15, 3, 3, 1)) # 15 line height for bottom margin
barplot(c(2, 4, 1, 6), main="Barplot", las=2,
names.arg=c("This is my first very long name",
"This is my second very long name",
"This is my third very long name",
"This is my fourth very long name"))
当horiz=TRUE
时,您可以使用las=1
并向左边距添加空格:
par(mar=c(3, 15, 3, 1))
barplot(c(2, 4, 1, 6), main="Barplot", las=1, horiz=TRUE,
names.arg=c("This is my first very long name",
"This is my second very long name",
"This is my third very long name",
"This is my fourth very long name"))
