No unfortunately. I think I was referring to #1520 (which I opened on the same day as the posts above), or a subsequent PR. I do hope to return to...

Here is the Gadfly way. The idea is to write an `apply_statistic` function for a `CandlestickStatistic`. You'll find examples in Gadfly's `statistics.jl` file, where the `apply_statistic` function adds a color_scale....

Also test this example (replace the appropriate lines above): ```julia scales = Dict{Symbol, Gadfly.ScaleElement}() color_scale = get(scales, :color, Scale.color_discrete_manual("red","green")) ``` Does it make sense?

For PRs it's also good to show an example png of your new feature [like this](https://github.com/GiovineItalia/Gadfly.jl/pull/1408#issue-395065082)

Hopefully I'll get around to looking at this soon (this week).

There's an [example on Julia Discourse](https://discourse.julialang.org/t/can-i-choose-display-software/29510/3) of one way to enable `set_default_plot_format`. I haven't tested that out on IJulia. Note IJulia creates it's own display, at the top of the...

I can't tell from your posts if you have found (for a specific Gadfly plot): ```julia p = plot(...) draw(PNG(8inch, 8inch), p) ```

Another example to keep in mind is `linestyle=[:dash]`, which could be interpreted as a categorical or functional variable.

Option 2 (typed"string" only syntax) + `color=colorant"red"` and `linestyle=linestyle"dash"`.
