Wrapping text in e_tooltip

[svenb78]

Hi,

it's me again. :-)

Given the following example:

library("dplyr")
library("echarts4r")

df <- data.frame(
  label = c(
    "This is a long label which should be wrapped for displaying"
    , "This is another label even longer which also should be wrapped"
  )
  , values = c(10, 40)
) %>%
  mutate(wrapped_label = stringr::str_wrap(label, 10))

plot_e <- df %>%
  e_charts(x = wrapped_label) %>%
  e_pie(serie = values) %>%
  e_legend(show = FALSE) %>%
  e_tooltip(trigger = "item")

plot_e

How can I wrap the text within the tooltip? Following the apache docu, I tried textStyle = list(width = 2, overflow = "break") but that did not work.

I haven't run your example yet (I must admit) but what exactly should the result be, what should the text be doing?

Does it help to use \n in the text perhaps? Something like this: "This is another label\neven longer which\nalso should be wrapped"

Running the example takes a minute ... :-)

I work with a data set on natural reserves (WDPA) and need to plot budget spend by reserve name. The data set is large, and the names are long. Adding line breaks manually is neither practicable nor good style.

Solution is to use these two together or alone in tooltip: extraCssText= 'white-space:pre-wrap;', confine= TRUE
