cannot create subplots of pie

[nesteiner]

Describe the bug
I have such code

using StatsBase, PlotlyJS, DataFrames
let nums = rand(1:10, 100)
  cm = countmap(nums)
  xs = collect(keys(cm))
  ys = collect(values(cm))

  df = DataFrame(xs = xs, ys = ys)

  p = PlotlyJS.pie(df, values = :ys, textposition = "inside")
  
  sp = make_subplots(rows = 1, cols = 2)
  add_trace!(sp, p, row = 1, col = 1)
  add_trace!(sp, p, row = 1, col = 2)
  sp
end

what I expect is that there are two pie plots in the figure,
however there is only one pie plot

When you define the plot, sp, you should set the specs, i.e. the type of trace for each subplot cell.
See also: https://github.com/sglyon/PlotlyBase.jl/blob/master/src/subplot_utils.jl#L155.

let nums = rand(1:10, 100)
  cm = countmap(nums)
  xs = collect(keys(cm))
  ys = collect(values(cm))

  df = DataFrame(xs = xs, ys = ys)

  p = PlotlyJS.pie(df, values = :ys, textposition = "inside")
  
  sp = make_subplots(rows = 1, cols = 2, specs =[Spec(kind="pie") for i=1:1, j in 1:2])
  add_trace!(sp, p, row = 1, col = 1)
  add_trace!(sp, p, row = 1, col = 2)
  sp
end

oh, thank you, it's my fault
