在ggplot中使用预定义的调色板 [英] Using a pre-defined color palette in ggplot
问题描述
有人知道如何在ggplot中使用预定义的调色板吗?
我有一个我想要使用的颜色矢量:
$ (#771C19,#AA3929,#E25033,#F27314,#F8A31B,#F8A31B,#E2C59F,#B6C5CC,#8E9CA3,#556670,#000000)
但是,当我试图将它传递给没有发生任何事情时
ggplot(mydata,aes(factor phone_partner_products)),color = rhg_cols)+
geom_bar()
aes()
内放置 color = rhg_cols
。据我所知,你想在横坐标上应用因子变量的梯度(barplot)?然后使用 fill
- 试试这个: ggplot(mydata,aes (因子(phone_partner_products),fill = factor(phone_partner_products)))+
geom_bar()+
scale_fill_manual(values = rhg_cols)
或尝试实现近似副本:
ggplot(mydata,aes(因子(phone_partner_products),fill = phone_partner_products)))+
geom_bar()+
scale_fill_gradient(low =#771C19,hi =#000000)
请注意,在第二种情况下,连续变量传递给 fill
美学,因此<$ c之后传递$ c> scale_fill_gradient 。如果您将因子
传递给 fill
aes,您必须坚持使用 scale_fill_manual(values = rhg_cols)
Does anyone know how to use a pre-defined color palette in ggplot?
I have a vector of colors I would like to use:
rhg_cols <- c("#771C19", "#AA3929", "#E25033", "#F27314", "#F8A31B",
"#E2C59F", "#B6C5CC", "#8E9CA3", "#556670", "#000000")
But when I try to pass it to nothing happened
ggplot(mydata, aes(factor(phone_partner_products)), color = rhg_cols) +
geom_bar()
You must put colour = rhg_cols
inside aes()
. As far as I can tell, you want to apply gradient to bars (in barplot) with factor variable on the abscissa? Then use fill
- try this instead:
ggplot(mydata, aes(factor(phone_partner_products), fill = factor(phone_partner_products))) +
geom_bar() +
scale_fill_manual(values = rhg_cols)
or try to achieve approximate replica with:
ggplot(mydata, aes(factor(phone_partner_products), fill = phone_partner_products))) +
geom_bar() +
scale_fill_gradient(low = "#771C19", hi = "#000000")
Notice that in second case a continuous variable is passed to fill
aesthetics, therefore scale_fill_gradient
is passed afterward. If you pass factor
to fill
aes, you must stick with scale_fill_manual(values = rhg_cols)
