ggplot2
数据准备
案例数据为某商品在多个平台的销量数据,插件会为销量数据自动降序排列绘制条形图,同时计算累积销量绘制累积折线图。
# 加载数据
data <- read.delim("files/Hiplot/133-pareto-chart-data.txt", header = T)
# 整理数据格式
data <- data[order(-data[["sales"]]), ]
data[["channel"]] <- factor(data[["channel"]], levels = data[["channel"]])
## 计算百分比
data$accumulating <- cumsum(data[["sales"]])
max_y <- max(data[["sales"]])
cal_num <- sum(data[["sales"]]) / max_y
data$accumulating <- data$accumulating / cal_num
