[英]Plot only y-axis but nothing else
I would like to create a plot where only the y-axis (including grids,numbers and label) is displayed. 我想创建一个只显示y轴(包括网格,数字和标签)的图。 But I do not want to display the plot or the x-axes. 但我不想显示图或x轴。
Is this possible to do? 这可能吗?
When creating your plot, you just need to specify a few options. 创建绘图时,只需指定几个选项即可。 In particular, note axes
, type
and xlab
: 特别是,音符axes
, type
和xlab
:
plot(runif(10), runif(10),
xlim=c(0, 1), ylim=c(0,1),
axes=FALSE, #Don't plot the axis
type="n", #hide the points
ylab="", xlab="") #No axis labels
You can then manually add the y-axis: 然后,您可以手动添加y轴:
axis(2, seq(0, 1, 0.2))
and add an grid if you desire 并根据需要添加网格
grid(lwd=2)
You can use geom_blank()
and theme adjustment to switch off unwanted elements: 您可以使用geom_blank()
和主题调整来关闭不需要的元素:
p <- ggplot(mtcars, aes(disp, mpg)) + geom_blank()
p + theme(axis.line.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank(),
axis.title.x=element_blank(),
panel.grid.minor.x=element_blank(),
panel.grid.major.x=element_blank())
Alternatively, if you already have a plot, you can extract the axis part with gtable
: 或者,如果您已经有一个绘图,则可以使用gtable
提取轴部分:
library(gtable)
g <- ggplotGrob(p)
s <- gtable_filter(g, 'axis-l|ylab', trim=F) # use trim depending on need
grid.newpage()
grid.draw(s)
You can simply use plot.new()
. 你可以简单地使用plot.new()
。
plot.new()
axis(2, seq(0, 1, 0.2))
grid(led = 2)
# etc
