尝试更改GGR中ggplot图的颜色
我试图复制下图中的甜甜圈图 除了实际的着色,我已经完成了所有的工作,对于我在ggplot的scale_colour_手册部分所做的错误,我感到困惑 以下是我用于ggplot的代码:尝试更改GGR中ggplot图的颜色,r,colors,ggplot2,donut-chart,R,Colors,Ggplot2,Donut Chart,我试图复制下图中的甜甜圈图 除了实际的着色,我已经完成了所有的工作,对于我在ggplot的scale_colour_手册部分所做的错误,我感到困惑 以下是我用于ggplot的代码: ggplot(base_ind_zones) + geom_rect(aes(fill = base_zones, ymax=ymax, ymin=ymin, xmax=4, xmin=3)) + geom_rect(aes(fill = ind, ymax=ymax, ymin=ymin
ggplot(base_ind_zones) +

和一个样本数据集:
base_ind_zones <- base_ind_zones = data.frame(category=c("A", "B", "C", "D"),
base_zones=c(33, 44, 12, 11),
ind=c(33, 44, 2, 21))
#Needed to determine the ymin and ymax for ggplot
base_ind_zones$fraction = base_ind_zones$ind / sum(base_ind_zones$ind)
base_ind_zones$ymax = cumsum(base_ind_zones$fraction)
base_ind_zones$ymin = c(0, head(base_ind_zones$ymax, n = -1))
base\u ind\u zonesbase\u ind\u zones由于映射了fill
您需要使用scale\u fill\u manual
调整填充颜色。
base_ind_zones <- data.frame(category=c("A", "B", "C", "D"),
base_zones=as.character(c(33, 44, 12, 11)),
ind=as.character(c(33, 45, 2, 21)),
stringsAsFactors = FALSE)
#Needed to determine the ymin and ymax for ggplot
base_ind_zones$fraction = as.numeric(base_ind_zones$ind) /
sum(as.numeric(base_ind_zones$ind))
base_ind_zones$ymax = cumsum(base_ind_zones$fraction)
base_ind_zones$ymin = c(0, head(base_ind_zones$ymax, n = -1))
ggplot(base_ind_zones) +
