Data Preparation

# Load data
data <- data.table::fread(jsonlite::read_json("https://hiplot.cn/ui/basic/waterfalls-plot/data.json")$exampleData$textarea[[1]])
data <- as.data.frame(data)

# convert data structure
data[["name"]] <- factor(data[["name"]], levels = data[["name"]])
data$fill <- ifelse(data$value > 0, "#B71C1C", "#1B5E20")

# View data
head(data)

  name value    fill
1    A   100 #B71C1C
2    B   -20 #1B5E20
3    C   120 #B71C1C
4    D   -40 #1B5E20
5    E  -100 #1B5E20
6    F    80 #B71C1C

Visualization

# Waterfalls Plot2
p <- waterfall(data, calc_total = T, rect_width = 0.7, fill_by_sign = F,
               fill_colours = data$fill, total_rect_color = "#1E065D") +
  theme_bw()
