r - r plotly - 如何防止悬停名称被截断

Question

由于名称过长，出现在我的情节图上悬停框外的悬停名称正在被截断。我找到了plotly.js和plotly.py但不是 R 的解决方案。我已经能够从悬停中删除该名称或将其移动到带有该值的框中，但需要一个解决方案，使其保持原位，同时允许整个名称可见。

# sample data
Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 1"
datTemp <- data.frame(Time, Value, Site)

Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 2"
datTemp2 <- data.frame(Time, Value, Site)

Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 3"
datTemp3 <- data.frame(Time, Value, Site)    

figTemp<-datTemp%>%
    plot_ly(x = ~Time, y = ~Value, type = "scatter", mode = "lines", line = list(width = 0.75), name = ~Site[1])%>%
    layout(xaxis = list(title = "Date"), yaxis = list(title = "Temperature (C)"), legend = list(x = 0, y = 1.05, orientation = "h"))

figTemp<-figTemp%>%
    add_trace(data = datTemp2, y = ~Value, type = "scatter", mode = "lines", name = ~Site[1])%>%
    add_trace(data = datTemp3, y = ~Value, type = "scatter", mode = "lines", name = ~Site[1])

添加hovertemplate = paste('(%{x}, %{y})')到您的通话中plot_ly。工作。尝试这个：

library(tidyverse)
library(plotly)
# sample data
Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 1"
datTemp <- data.frame(Time, Value, Site)

Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 2"
datTemp2 <- data.frame(Time, Value, Site)

Value <- rnorm(100, mean = 5)
Time <- c(1:100)
Site <- "Really long name for Site 3"
datTemp3 <- data.frame(Time, Value, Site)    

figTemp<-datTemp%>%
  plot_ly(x = ~Time, y = ~Value, type = "scatter", mode = "lines", line = list(width = 0.75), name = ~Site[1],
          hovertemplate = paste('(%{x}, %{y})')) %>%
  layout(xaxis = list(title = "Date"), yaxis = list(title = "Temperature (C)"), legend = list(x = 0, y = 1.05, orientation = "h"))

figTemp<-figTemp%>%
  add_trace(data = datTemp2, y = ~Value, type = "scatter", mode = "lines", name = ~Site[1]) %>%
  add_trace(data = datTemp3, y = ~Value, type = "scatter", mode = "lines", name = ~Site[1])

figTemp
