I have got the answer as below , just mark it .

 library(waterfalls)
    
    plot_data <- data.frame(category = letters[1:5],
                            value = c(1, -0.2, 0.3, -0.1, -0.15))
    
    waterfall(.data = plot_data,
              fill_colours = colorRampPalette(c("#1b7cd6", "#d5e6f2"))(5),
              fill_by_sign = FALSE,
              calc_total = TRUE,
              total_axis_text='total',
              rect_text_labels=scales::percent(plot_data$value,0.1),
              total_rect_text = scales::percent(sum(plot_data$value),0.1))
