Unintended highlight with e_map timeline

[psimm]

When a chart has a choropleth map and a timeline, clicking on the timeline dots highlights countries. This is a new behavior that does not occur on the last CRAN release.

Example:

library(dplyr)
library(echarts4r)

choropleth <- data.frame(
  countries = rep(c("United States", "Russia", "Brazil"), 2),
  date = rep(c(as.Date("2021-01-01"), as.Date("2021-01-02")), each = 3),
  values = runif(6)
)

choropleth %>%
  group_by(date) %>%
  e_charts(countries, timeline = TRUE) %>%
  e_map(values) %>%
  e_visual_map(min = 0, max = 1)

On initial load:

After clicking the second timeline dot (and not clicking on Russia):

Clicking on the arrows does not trigger the highlight. It seems that the timeline dot has an unintentional connection to the other plot data.

This behavior can also be seen on the website: https://echarts4r.john-coene.com/articles/timeline.html#general-options

Interesting. That seems to be from echarts.js itself as far as I can tell but I will have to dig in a little more.

Funny, I received an email notification from Github about a comment from @jordancampbell23 on e_timeline_opts( axis_type = "time") fixing the issue but I don't see the comment on here.

Yes, my bad. I got rid of a similar issue on another timeline--but it didn't resolve this issue.

[JohnCoene]

No problem @jordancampbell23 :)

recognized as bug in ECharts v.5+

@JohnCoene one way around the distraction of this bug is to disable select in e_map by adding the following:

select = list(disabled = T)

I don't find the select feature adds much to the maps, so personally it has minimal downside.
