我正在尝试使用R为Shiny仪表板绘制一个明暗的朝阳图。这是一个简单的图,用于可视化已发生的支出类型及其子类别。该代码运行正常,但是我在工具提示中得到了一些奇怪的附加文本-在所有提示旁边都显示“ Trace 0”。
我已经尝试了工具提示格式的多种变体,但无济于事。我怀疑问题出在数据框的格式上,尽管这是基于Plotly网页中的示例,如果我更改它,该图将不会显示。
这是一些最低限度的可复制代码。
library(plotly)
example_df <- structure(
list(
type = structure(
c(6L, 5L, 5L, 5L, 5L, 1L, 1L,
2L, 2L, 2L, 3L, 3L, 4L, 4L),
.Label = c("Food", "Fun", "Services",
"Transport", "Expenses", ""),
class = "factor"
),
subtype = structure(
c(14L, 13L, 12L, 11L, 10L, 6L, 8L, 2L, 3L, 5L, 4L, 7L, 1L, 9L),
.Label = c(
"Car", "Bar", "Drinks", "Entertainment", "Books",
"Restaurant", "Cleaning", "Market", "Trip", "Food", "Fun",
"Services", "Transport", "Expenses"),
class = "factor"
),
cost = c(13969, 5776, 1561, 2822, 3810, 2145, 1665, 1150, 1037, 635,
955, 606, 1334, 4442)
),
row.names = c(NA, -14L),
class = c("tbl_df", "tbl", "data.frame")
)
plot_ly(example_df,
labels = ~subtype,
parents = ~type,
branchvalues = 'total',
values = ~cost,
type = 'sunburst',
hovertemplate = paste('<b>%{label}</b><br>', '%{value:$,.0f}'))
运行前面的代码时,我得到一个类似in this image的图形。我希望完全一样,但没有奇怪的“ trace 0”文本。
答案 0 :(得分:0)
您可以将名称设置为空,
plot_ly(example_df,
labels = ~subtype,
parents = ~type,
branchvalues = 'total',
name = "",
values = ~cost,
type = 'sunburst',
hovertemplate = paste('<b>%{label}</b><br>', '%{value:$,.0f}'))
或者这也可行,
plot_ly(example_df,
labels = ~subtype,
parents = ~type,
branchvalues = 'total',
name = "",
values = ~cost,
type = 'sunburst',
hoverinfo = "text",
hovertext = ~paste0("<b>",subtype,"</b><br>",cost))
