I’m experiencing the same issue. Code below. This appears to be a bug, since the same question has popped up in the plotly for Python forum topic as well.
sunburst_data <- data.frame(ids = c(1, 2, 3, 4, 5, 6, 7, 8, 9, “1 - a”, “1 - b”, “2 - a”, “2 - b”, “3 - a”, “3 - b”, “4 - b”, “5 - a”, “5 - b”, “6 - a”, “6 - b”, “7 - a”, “7 - b”, “8 - a”, “8 - b”, “9 - a”, “9 - b”),
labels = c(“Group 1”, “Group 2”, “Group 3”, “Group 4”, “Group 5”, “Group 6”, “Group 7”, “Group 8”, “Group 9”, “a”, “b”, “a”, “b”, “a”, “b”, “b”, “a”, “b”, “a”, “b”, “a”, “b”, “a”, “b”, “a”, “b”),
parents = c("", “”, “”, “”, “”, “”, “”, “”, “”,“1”, “1”, “2”, “2”, “3”, “3”, “4”, “5”, “5”, “6”, “6”, “7”, “7”, “8”, “8”, “9”, “9”),
values = c(195, 99, 2425, 3, 379, 5182, 48, 3119, 903, 37, 158, 15, 84, 561, 1864, 3, 67, 312, 915, 4267, 19, 29, 433, 2686, 51, 852), stringsAsFactors = F)
plot_ly(sunburst_data, ids=~ids, labels=~labels, parents=~parents, values=~values, type=“sunburst”, branchvalues=“total”)
