Hello,
I'm trying to add a chart as a tooltip when clicking on my data point in a map.
For this I'm using the leaflet package to create a map and the data point on a specific location and the chart as a tooltip comes from the highcharter package. I'm basically trying to get the same result as discussed in this link on StackOverflow: https://stackoverflow.com/questions/59173708/r-leaflet-highcharter-tooltip
This is the piece of code that is used in my custom visual based in R, so with RHTML ->
source('./r_files/flatten_HTML.r')
############### Library Declarations ###############
libraryRequireInstall("leaflet");
libraryRequireInstall("sf");
libraryRequireInstall("htmlwidgets");
libraryRequireInstall("dplyr");
libraryRequireInstall("stringr");
libraryRequireInstall("htmltools");
libraryRequireInstall("highcharter");
as.character.htmlwidget <- function(x, ...) {
htmltools::HTML(
htmltools:::as.character.shiny.tag.list(
htmlwidgets:::as.tags.htmlwidget(
x
),
...
)
)
}
add_deps <- function(dtbl, name, pkg = name) {
tagList(
dtbl,
htmlwidgets::getDependency(name, pkg)
)
}
Leaflet_Map <- leaflet()
Leaflet_Map <- addProviderTiles(Leaflet_Map, providers$CartoDB)
Leaflet_Map <- addCircleMarkers(Leaflet_Map, lat = 45.4, lng = 14.9,
popup = list(paste(as.character(
hchart(data.frame(x = 1:10, y = 1:10), type = "line", hcaes(x = x, y = y)) %>% hc_size(width = 300, height = 200)
))),
popupOptions = popupOptions(minWidth = 300, maxHeight = 200))
Leaflet_Map <- onRender(Leaflet_Map,
"
function(el,x) {
this.on('popupopen', function() {HTMLWidgets.staticRender();})
}
") %>% add_deps("highchart", 'highcharter') %>% browsable()
############# Create and save widget ###############
internalSaveWidget(Leaflet_Map, 'out.html')
The problem is that the piece of code 'add_deps("highchart", 'highcharter')' gives me the error. If I remove it, I'm almost getting the right result which is an empty box.
But when I use the full code with the adding of 'add_deps("highchart", 'highcharter')', I get this error:
My first thought was to change something in the function internalSaveWidget which resides in the 'flatten_HTML.r' file.
Can somebody help me with this problem please?
Hi @naelske_cronos ,
Please refer to this blog to check whether your highchart option is correct.
For reference: What is highcharter?
Here is a similar post like yours about how to add tooltips in Power BI custom R visual.

I hope they could help you solve your problem.

Hello @v-rzhou-msft
I don't have enough with this information. I thought having more information about the error in the code but no problem. I'll not accept this as an answer to my solution but thanks for your reply.
I used another method to show a tooltip with the R custom visual and this is saving a plot with the ggplot package to a SVG file. This works perfectly!
Kind regards
