Using POSIXct in echarty

[jack-davison]

Hello!

I can't find an example anywhere of using datetimes, and am struggling to get it to work.

now <- Sys.time()

times <- now + (3600 * c(1, 5, 20, 100, 200))

df <-
  data.frame(
    x = times,
    y = 1:5
  )

echarty::ec.init(
  preset = FALSE,
  xAxis = list(
    data = df$x
  ),
  series = list(list(
    name = "y",
    type = "line",
    stack = "total",
    data = df$y
  ))
)

This makes this, which is wrong.

This can be seen if you compare to ggplot2.

Are POSIXCt objects supported by echarty? If so, where am I going wrong?

Thanks,
Jack

The main problem in the code is that series' data could be one-dimensional only for X-axis of type 'category', not type 'time'.
The easiest fix would be to use a dataset by adding df to ec.init like so:

echarty::ec.init( df,
  # xAxis = list(type='time'),   # inferred from df$x and automatically added 
  series = list(list(
    name = "y",
    type = "line"
  ))
)
