Facet function in highcharts


I have a data like this example:

df <-
  data.frame(
    date = seq(as.Date("2015-01-01"), as.Date("2015-12-31"), 100),
    id = rep(LETTERS, each = 4)[1:100],
    replicate(2, sample(1001, 100))
  )

Plotting with ggplot is Ok

ggplot(df, aes(x = date)) +
  geom_line(aes(y = X1)) +
  geom_line(aes(y = X2), linetype = 2) +
  facet_wrap( ~ id , scales = "free") 

I found some info about facet implementation in highchart higcharter-grid-test and I tried to plot it with highchart in order to make an interactive plot, but highchart::hw_grid() and browsable() are deprecated. Can anybody help me with ploting my data?

My snippet :

  highchart() %>% 
    hc_add_series(name = "X1", data = df$X1) %>% 
    hc_add_series(name = "X2", data = df$X2) %>% 
    hw_grid(id, rowheight = 200, ncol = 3)

Solution

  • hw_grid and browsable approach seems to work still for me.

    library(tidyverse)
    library(highcharter)
    
    # Create data
    df <-
      data.frame(
        date = seq(as.Date("2015-01-01"), as.Date("2015-12-31"), 100),
        id = rep(LETTERS, each = 4)[1:100],
        replicate(2, sample(1001, 100))
      )
    
    # Reshape long format
    df_long <-
      df %>%
      pivot_longer(cols = c("X1", "X2"))
    
    # Check
    head(df_long, 12)
    
    #> # A tibble: 12 x 4
    #>    date       id    name  value
    #>    <date>     <chr> <chr> <int>
    #>  1 2015-01-01 A     X1      490
    #>  2 2015-01-01 A     X2      868
    #>  3 2015-04-11 A     X1      422
    #>  4 2015-04-11 A     X2      751
    #>  5 2015-07-20 A     X1      958
    #>  6 2015-07-20 A     X2       52
    #>  7 2015-10-28 A     X1      486
    #>  8 2015-10-28 A     X2      680
    #>  9 2015-01-01 B     X1      631
    #> 10 2015-01-01 B     X2      425
    #> 11 2015-04-11 B     X1      532
    #> 12 2015-04-11 B     X2      402
    

    Now highcharter

    Iterate plotting code over each letter, storing outputs in a list

    list_of_plots <- map(LETTERS, function(x) {
      
      filtered <-
        df_long %>%
        filter(id == x)
    
      highchart() %>%
        hc_add_series(data = filtered,
                      hcaes(x = date, y = value, group = name),
                      type = "line") %>%
        hc_title(text = x)   
      
      })
    
    # Then pass final list to `hw_grid` function.
    
    hw_grid(list_of_plots, rowheight = 300) %>%
      htmltools::browsable()
    

    Here's (some of) the output:
