no method `get(::String, ...)` for PlotlyJS on dataframe

[mzaffalon]

I am following along the Dash tutorial for Julia and I have an error on the following piece of code

using DataFrames, PlotlyBase, UrlDownload

df1 = DataFrame(urldownload("https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv"))

Plot(df1[df1.year .== 2002, :],
                          Layout(xaxis_type = "log",
                                 xaxis_title = "GDP Per Capita",
                                 yaxis_title = "Life Expectancy",
                                 legend_x = 0,
                                 legend_y = 1,
                                 hovermode = "closest",
                                 transition_duration = 500),
                          x = :gdpPercap,
                          y = :lifeExp,
                          text = :country,
                          group = :continent,
                          mode = "markers",
                          marker_size = 15,
                          marker_line_color = "white")

My feeling is that who edited this example pasted the code and mixed data and layout. It is missing chart type (scatter, bar,...).

[mzaffalon]

There is indeed a method Plot(df, layout; style, kargs...) described in the manual.

Thanks for opening! THis is a bug I will fix up today

BTW new dash julia docs are in the works and will be released soon, so stay tuned

[mzaffalon]

Thank you for fixing it quickly!
