我如何更改ggplot2图例的标题? [英] How can I change the title of a ggplot2 legend?
问题描述
我在寻找这里,但我无法弄清楚。
如何将单词类型更改为其他内容?
+ labs(color =legend title)
到您的ggplot调用。
伟大的资源网站也是 ggplot2的谷歌组。
编辑:这里假设颜色是图例中的美学,例如 qplot(X,Y,颜色= Z)
。如果在图例中显示另一种美学,则将其用作参数,例如, + labs(fill =legend title)
用于栅格/图像绘图。 b
$ b
更一般地说,如果你指定一个显式比例如 scale_colour_continuous
,你可以设置 scale_name
参数( warning ):在最近的版本 ggplot2
中,缩放参数的详细信息可能已更改; this描述的版本是0.9.2.1)。
I was looking here but I can't figure it out.
How can I change the word "type" to something else?
Add
+ labs(colour = "legend title")
to your ggplot call. Great resource site is also google group for ggplot2.
edit: this assumes that colour is the aesthetic in the legend, e.g. qplot(x,y,colour=z)
. If another aesthetic is being shown in the legend, use that as the argument instead, e.g. + labs(fill = "legend title")
for a raster/image plot.
More generally, if you specify an explicit scale such as scale_colour_continuous
, you can set the scale_name
argument (warning: the details of the arguments to scales may have changed in recent releases of ggplot2
; this description is of version 0.9.2.1).
