Plots integration

[PhilipVinc]

With some painful reverse engineering, I realised that we can use Plots.jl to integrate with StripplePlotly with the following:

using Mesurements
using Plots

function to_plotly_base(pl)
  pl = Plots.plotlybase_syncplot(pl)
  delete!(pl.layout.fields, :height)
  delete!(pl.layout.fields, :width)
  pl.layout.fields[:margin] = Dict(:l=>50, :b=>50, :r=>50, :t=>60)
  return pl
end

# generate data with errors
y = Measurements.measurement(rand(10), rand(10)*0.1)

# use recipes from plots.jl
plt = plot(1:10, y)

# this object now is a PlotlyBase.Plot and can be used with Stripple
plt = to_plotly_base(plt)

# update the model
model.plot_data[] = plt.data
model.plot_layout[] = plt.layout

It would be nice if this could be done automatically.

(The margins are the default from PlotlyBase, because the default from Plots jl get cropped when using them with stripple)

Thanks for sharing this, definitely worth digging into it!

PlotlyJS.jl are wrap of PlotlyBase.jl. The good is that the data and layout fields from PlotlyBase behave same as they do in plot of StipplePlotly.

BTW: I cannot find Plots.plotlybase_syncplot .

julia> using Plots

julia> Plots.plotlybase_syncplot

It's in here.
I guess it's being lazy loaded so you might have to run Plots.plotly() first ?

[PhilipVinc]

Confirmed.
You must have PlotlyBase in your project too, and run Plots.plotly().

Just want to add a hint that there is pop! to delete a field from a layout. In this case your implementation is probably the fastest you can do, but it may break if the internals of the package change, e.g. when one should decide to move away from the fields structure. So your function could read:

function to_plotly_base(pl)
  if isdefined(Plots, :plotlybase_syncplot)
    current_backend = Plots.backend()
    Plots.plotly() === current_backend || Plots.backend(current_backend)
  end

  pl = Plots.plotlybase_syncplot(pl)
  pop!(pl.layout, :height)
  pop!(pl.layout, :width)
  pl.layout.fields[:margin] = Dict(:l=>50, :b=>50, :r=>50, :t=>60)
  return pl
end

Anyhow, I proposed a PR to also add a delete!()method to PlotlyBase.
