exampleplots.jl's Issues

The exponential color scale is broken

Hi!

I like Plots.jl a lot, and I'm trying to use it for academic purposes, unfortunatley I think I just caught a bug running the examples from there :

C(g::ColorGradient) = RGB[g[z] for z=(-1:0.1:1)]
g = :inferno
cgrad(g, scale=:log) |> C

outputs the right thing, but

cgrad(g, scale=:exp) |> C

threw this at my poor face:

MethodError: no method matching -(::Array{Float64,1}, ::Int64)
Closest candidates are:
  -(!Matched::Complex{Bool}, ::Real) at complex.jl:298
  -(!Matched::Missing, ::Number) at missing.jl:93
  -(!Matched::Base.CoreLogging.LogLevel, ::Integer) at logging.jl:107
  ...

Stacktrace:
 [1] #cgrad#21(::Nothing, ::Symbol, ::Function, ::Symbol) at C:\Users\user\.julia\packages\PlotUtils\GxT73\src\color_gradients.jl:222
 [2] (::getfield(PlotUtils, Symbol("#kw##cgrad")))(::NamedTuple{(:scale,),Tuple{Symbol}}, ::typeof(cgrad), ::Symbol) at .\none:0

Thanks for your time!

Are the example files generated?

More of a question than issue. I was just wondering if the example files are generated by a script based on the "supported.jl" file? Or how do you automate this? Thanks

Example `notebooks/series_recipes.ipynb` does not work

It seems that syntaxis has changed as some point (I am with julia 1.1, Plots v0.26.0).

@recipe function f(::Type{Val{:my_histogram}}, x, y, z)
    edges, counts = myhist!(d) # leads to the error

The error is UndefVarError: d not defined

I do not see with @macroexpand how the d would appear in there
