Simple Bar chart

using InMemoryDatasets, StatisticalGraphics, DLMReader

Bar produces bar chart, by default it assigns the frequency of each value to the height of the corresponding bar

movies = filereader(joinpath(dirname(pathof(StatisticalGraphics)),
                                 "..", "docs", "assets", "movies.csv"),
                                 dlmstr="::")
sgplot(movies, Bar(x="Major Genre"))

To produce horizontal bar chart, pass the analysis variable to y

sgplot(movies, Bar(y="Major Genre"))

A response column can be pass to Bar when the analysis variable is different from categories. By default the sum of the response column will be used as the height of each bar. User can pass any function in the form of (f, x)->... to stat to customise the aggregation of response

##IMD.maximum handles missing values
sgplot(movies, Bar(y="Major Genre", response="Worldwide Gross", stat=IMD.maximum))

User can control the order of bars by passing orderresponse. Bar automatically aggregate the values of orderresponse in each category and arrange the category in the final output accordingly.

sgplot(movies, Bar(y="Major Genre", response="Worldwide Gross",
                     stat=IMD.maximum, orderresponse="Worldwide Gross",
                     orderstat=IMD.maximum))

Similar to other marks there are many keyword arguments to fine tune the final output

sgplot(movies, Bar(y="Major Genre", response="Worldwide Gross",
                     stat=IMD.maximum, orderresponse="Worldwide Gross",
                     orderstat=IMD.maximum, colorresponse="Worldwide Gross",
                     colorstat=mean,
                     colormodel=Dict(:scheme=>:blues)))

And

sgplot(movies, Bar(y="Major Genre", response="Worldwide Gross",
                     stat=IMD.maximum, orderresponse="Worldwide Gross",
                     orderstat=IMD.maximum, colorresponse="Worldwide Gross",
                     colorstat=mean,
                     colormodel=Dict(:scheme=>:browns),
                     barcorner=[0,5,0,5],
                     space=0.4,
                     outlinecolor=:black,
                     legend=:bar_leg,
                     missingmode=1
                     ),
                     xaxis=Axis(title="Maximum Worldwide Gross",
                        domain=false, d3format="\$,f", grid=true),
                     yaxis=Axis(domain=false, grid=true),
                     legend=Legend(name=:bar_leg, d3format="\$,f",
                        title="Average Worldwide Gross", orient=:bottom,
                     direction=:horizontal, gradientlength=600),
                     clip=false)
