情节错误条情节奇怪的配色方案答案

【问题描述】：

我观察到plotly::plot_ly 的一个奇怪选择是在指定组着色时为误差条着色：

library("data.table")
library("plotly")
dat <- data.table(
  low_diff = c(2, 3, 1)
  , high_diff = c(3, 4, 1)
  , point = c(10, 11, 9)
  , type = LETTERS[1:3]
)
plot_ly(data = dat, y = type, x = point, mode = "markers", color = type,
        error_x = list(type = "data", symmetric = FALSE,
                       array = high_diff, arrayminus = low_diff))

如何指定每个点的颜色应与其误差线相同？

【解决方案1】：

如果您有color = type，请切换到group = type 以获得所需的分组。

plot_ly(data = dat, y = type, x = point, mode = "markers", group = type,
        error_x = list(type = "data", symmetric = FALSE,
                       array = high_diff, arrayminus = low_diff))
