data <- read.delim("files/Hiplot/185-waterfalls-plot-data.txt", header = T)

# 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

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()
