R 华夫格图不显示一组

我使用

库（华夫格）

我的问题是姓氏组没有出现。我使用的代码如下

counts<-c(135.92, 15.98, 14.97, 14.15, 5.82, 11.82, 0.07 )
counts_names<-sprintf("%s (%s)", c("Coal", "Gas", "Wind", "Hydro", "Grid-scalar solar", "Rooftop solar", "Storage systems"), 
                  scales::percent(round(counts/sum(counts), 4)))
names(counts)<-counts_names
Generation_graph<-waffle(counts)+ scale_fill_tableau(name=NULL)

---

问题是，你的第七类的价值只是太小，无法在情节中体现出来。最后一个不带标签的组只是反映默认情况下由华夫格添加的“正方形”，以“填充”最后一列

根据您想要实现的目标，有几种选择：

#>加载所需包：ggplot2

计数您可以使用
scale\u fill\u manual（）

library(ggthemes)
library(waffle)
counts<-c(135.92, 15.98, 14.97, 14.15, 5.82, 11.82, 0.07 )
counts_names<-sprintf("%s (%s)", c("Coal", "Gas", "Wind", "Hydro", "Grid-scalar solar", "Rooftop solar", "Storage systems"), 
                      scales::percent(round(counts/sum(counts), 4)))
names(counts)<-counts_names
Generation_graph<-waffle(counts) + 
  scale_fill_manual(values = c("red", "blue", "green", "purple", "pink", "yellow", "orange", "blue"),
                    labels = counts_names, 
                    drop = TRUE)
