I see a lot of examples in javascript but I cannot find an example to do it in R
Here is the api link: http://api.highcharts.com/highcharts#global
I am tryin
The highcharter options can be accessed, but they are set inside the standard R options under the list element highcharter.options. They are not given directly to the highchart, and inside highchart(), there is the code line opts <- getOption("highcharter.options", list()).
I don't think there is another way than just get the options, alter whatever options you need to change and then set the options again with your additions.
The following is a simple illustration:
library(highcharter)
# normal highchart
highchart() %>%
hc_add_serie_labels_values(1:901, seq(1, 10, 0.01))
opts <- getOption("highcharter.options")
opts$lang$decimalPoint <- "."
options(highcharter.options = opts)
# now with "," instead of "." (confirm in tooltip)
highchart() %>%
hc_add_serie_labels_values(1:901, seq(1, 10, 0.01))
Of course in your case, you need to set the $global$timezoneOffset part.
