从颜色中移除线条并填充图例 [英] Remove lines from color and fill legends
问题描述
我有一个有三个不同图例的情节:一个用于 linetype
,一个用于 color
,另一个用于填
。在颜色
和填充
传说中,还有一些我希望删除的行,但是如何?
以下是一些示例代码:
#some data
hline_df< - data.frame(name = c('a','b'),y = c(1,2))
df < - data.frame(x = c(1, 2),y = c(0.5,1.5),con = c('a','b'),col = c('d','e'))
#plot
ggplot(df,aes(x,y,fill = con))+
geom_bar(stat ='identity')+
geom_point(aes(color = col))+
geom_hline(data = hline_df,aes(yintercept = y,linetype = name),
color ='red',show_guide = TRUE)
我得到两个红线的名称指南,这是罚款。
col指南有红线横过点,我想删除它们!
con指南也有红线,应该删除。
我可以用
$ b修改部分图例$ b
指南(fill = guide_legend(overrid e.aes = list(color = NULL)),
color = guide_legend(override.aes = list(color = NULL)))
这会消除颜色,但是线条仍然存在。
预先感谢!
您可以设置 linetype = 0
或blank
(不同于 linetype
s 在这里)为填充
和颜色
指南
s中的 override.aes
调用。
另外请注意,我移动了填充
ggplot
到 geom_bar中
aes
。
ggplot(df,aes(x,y))+
geom_bar aes(fill = con),stat ='identity')+
geom_point(aes(color = col))+
geom_hline(data = hline_df,aes(yintercept = y,linetype = name) ='red',show_guide = TRUE)+
guides(fill = guide_legend(override.aes = list(linetype = 0)),
color = guide_legend(override.aes = list(linetype = 0)))
I have a plot with three different legends: one for linetype
, one for color
, and one for fill
. In the color
and fill
legends there are also some lines which I wish to remove, but how?
Here is some example code:
# some data
hline_df <- data.frame(name = c('a', 'b'), y = c(1, 2))
df <- data.frame(x = c(1, 2), y = c(0.5, 1.5), con = c('a', 'b'), col = c('d', 'e'))
# the plot
ggplot(df, aes(x, y, fill = con)) +
geom_bar(stat = 'identity') +
geom_point(aes(color = col)) +
geom_hline(data = hline_df, aes(yintercept = y, linetype = name),
color = 'red', show_guide = TRUE)
I get the "name" guide for both red lines, that is fine.
The "col" guide has red lines crossing the dots, I want to remove them!
The "con" guide also has red lines which should be removed.
I could modify parts of the legend with
guides(fill = guide_legend(override.aes = list(colour = NULL)),
color = guide_legend(override.aes = list(colour = NULL)))
This removes the colour, but the lines are still there.
Thanks in advance!
You may set linetype = 0
or "blank"
(on different linetype
s here) for the fill
and color
guide
s in your override.aes
call.
Also note that I moved the fill
aes
from the 'top level' in ggplot
to geom_bar
.
ggplot(df, aes(x, y)) +
geom_bar(aes(fill = con), stat = 'identity') +
geom_point(aes(color = col)) +
geom_hline(data = hline_df, aes(yintercept = y, linetype = name), color = 'red', show_guide = TRUE) +
guides(fill = guide_legend(override.aes = list(linetype = 0)),
color = guide_legend(override.aes = list(linetype = 0)))
