Hi there,
Here is an interesting test case using an example from the Highcharts website regarding the boost option and a large number of datapoints (500/1.000k +),
Below an example Shiny application that does two things:
Using this application it should be possible to replicate the following: the first vanilla JS chart loads in < 1s, but once the second Shiny based chart has loaded the vanilla JS chart takes a much longer time.
Moreover, recreating the vanilla JS chart entirely in R Shiny using the highcharter package and hc_boost(enabled = TRUE) also results in very slow behaviour. Could it be that the boost module does not function as expected when using the highcharter library?
I would be very interested in knowing how to improve performance when using highcharter. The example below uses the latest versions of shiny, shinyjs, dplyr, highcharter and ggplot2, I cannot provide more details at this moment but may be able to do so later.
Best regards, Michael
