Daru::View

Daru (Data Analysis in RUby) is a library for analysis, manipulation and visualization of data. Daru-view is for easy and interactive plotting in web application & IRuby notebook. It can work in frameworks like Rails, Sinatra, Nanoc and hopefully in others too.

It is a plugin gem to Data Analysis in RUby(Daru) for visualisation of data

Examples :

Installation

Add this line to your application's Gemfile:

'daru-view', git: 'https://github.com/SciRuby/daru-view'

And then execute:

$ bundle

Or install it yourself as:

$ gem install daru-view

If above is not working or you want to install latest code:

install specific_install
specific_install https://github.com/SciRuby/daru-view

Usage

Use in IRuby notebook

Create separate folder and Gemfile inside it. Add minimum these lines in it

ce "http://rubygems.org"

uby dependencies
'rbczmq'
'ffi-rzmq'
'iruby'

tch from the github master branch
'daru-view', :git => 'https://github.com/SciRuby/daru-view'

"daru", git: 'https://github.com/SciRuby/daru.git'
"nyaplot", git: 'https://github.com/SciRuby/nyaplot.git'
'google_visualr', git: 'https://github.com/winston/google_visualr.git'
'daru-data_tables', git: 'https://github.com/Shekharrajak/daru-data_tables.git'

Now do bundle install and run iruby notebook
You may like to try some examples that is added in specs : spec/dummy_iruby/

Use in web application

Add this line in your Gemfile :

gem 'daru-view', :git => 'https://github.com/sciruby/daru-view.git'

gem “daru”, git: 'https://github.com/SciRuby/daru.git' gem “nyaplot”, git: 'https://github.com/SciRuby/nyaplot.git' gem 'google_visualr', git: 'https://github.com/winston/google_visualr.git' gem 'daru-data_tables', git: 'https://github.com/Shekharrajak/daru-data_tables.git'

e_ : Right now, in daru-view gemspec file `daru` and `nyaplot` is not added as development_dependency. Since daru-view required the latest github version of the Daru and Nyaplot gem and we can't fetch gem from the github in the gemspec.

 Rails application

 controller, do the data analysis process using daru operations and get the DataFrame/Vectors.

t a plotting library using e.g. `Daru::View.plotting_library = :highcharts`

 view, add the required JS files (for the plotting library), in head tag (generally) using the line , e.g. : `Daru::View.dependent_script(:highcharts)`

line `<%=raw Daru::View.dependent_script(:highcharts) %>` for rails app , must be added in the layout file of the application.

ot library using by passing `data` and `options` :

Charts example :

set the library, to plot charts

Daru::View.plotting_library = :highcharts

options for the charts

opts = {

  chart: {defaultSeriesType: 'line'},
  title: {
    text: 'Solar Employment Growth by Sector, 2010-2016'
    },

  subtitle: {
      text: 'Source: thesolarfoundation.com'
  },

  yAxis: {
      title: {
          text: 'Number of Employees'
      }
  },
  legend: {
      layout: 'vertical',
      align: 'right',
      verticalAlign: 'middle'
  },

  plotOptions: {
      # this is not working. Find the bug
      # series: {
      #     pointStart: 43934
      # }
  },

}

data for the charts

series_dt = ([{

  name: 'Tokyo',
  data: [7.0, 6.9, 9.5, 14.5, 18.4, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]

}, {

  name: 'London',
  data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]

}])

initialize

@line_graph = Daru::View::Plot.new(series_dt, opts)

Add this line in your view file, where you want to see you graph in web application. (It will put the html code of the line graph in web page)

<%=raw @line_graph.div %>

Now refresh the page, you will be able to see your graph.

lot example :

set the library, to plot charts (Default it is nyaplot only)

Daru::View.plotting_library = :nyaplot

options for the charts

opts = { type: :bar }

Vector data for the charts

data_vector = Daru::Vector.new [:a, :a, :a, :b, :b, :c], type: :category data_df = Daru::DataFrame.new({ a: [1, 2, 4, -2, 5, 23, 0], b: [3, 1, 3, -6, 2, 1, 0], c: ['I', 'II', 'I', 'III', 'I', 'III', 'II'] }) data_df.to_category :c

initialize

@bar_graph1 = Daru::View::Plot.new(data_vector ,opts) @bar_graph2 = Daru::View::Plot.new(data_df, type: :bar, x: :c)

Add this line in your view file, where you want to see you graph in web application. (It will put the html code of the line graph in web page)

<%=raw @bar_graph1.div %> <%=raw @bar_graph2.div %>

Now refresh the page, you will be able to see your graph.

er can try examples, that is added in [Demo web applicatioons (Rails, Sinatra, Nanoc)](https://github.com/Shekharrajak/demo_daru-view). To setup the rails app, run following commands :

bundle install bundle exec rails s

go to the http://localhost:3000/nyaplot to see the Nyaplot examples or http://localhost:3000/highcharts and similarly for googlecharts, datatables
ee the Highcharts examples.


 Sinatra application


 view, add the required JS files (for the plotting library), in head tag (generally) using the line , e.g. : `Daru::View.dependent_script(:highcharts)`

line `<%= Daru::View.dependent_script(:highcharts) %>` for sinatra app , must be added in the layout file of the application(inside the head tag).

In side the `app.rb` user must do data analysis process using daru features and define the Daru::View::Plot class instance variables to pass into the webpages in the `view` files. You will understand this better, if you will try to run sinatra app present in the `[Demo web applicatioons (Rails, Sinatra, Nanoc)](https://github.com/Shekharrajak/demo_daru-view)`

Add this line in your view file, where you want to see you graph in web application. (It will put the html code of the line graph in web page)

<%= @line_graph.div %>

<%= @bar_graph1.div %> <%= @bar_graph2.div %>

Now refresh the page, you will be able to see your graph.

er can try examples, that is added in [Demo web applicatioons (Rails, Sinatra, Nanoc)](https://github.com/Shekharrajak/demo_daru-view). To setup the rails app, run following commands :

bundle install bundle exec ruby app.rb

go to the http://localhost:4567/nyaplot to see the Nyaplot examples or http://localhost:4567/highcharts to see the Highcharts examples.


 Nanoc application

 of the things similar to Rails application (syntax of the view part of the application).

er can try examples, that is added in [Demo web applicatioons (Rails, Sinatra, Nanoc)](https://github.com/Shekharrajak/demo_daru-view). To setup the rails app, run following commands :

bundle install bundle exec nanoc bundle exec nanoc view

go to the http://localhost:3000/nyaplot to see the Nyaplot examples or http://localhost:3000/highcharts and similarly for googlecharts, datatables
ee the Highcharts examples.


 Live demo links

c web application complie and generates the html code of the nanoc web application. So you can see the running Nanoc app here :

 : There is some problem in nyaplot (in live link. It works fine locally). Some css is not working so some styling ain't working properly. You can see it properly in local setup.

ex.html](https://sciruby.github.io/daru-view/spec/dummy_nanoc/output/)

plot](https://sciruby.github.io/daru-view/spec/dummy_nanoc/output/nyaplot)

hcharts](https://sciruby.github.io/daru-view/spec/dummy_nanoc/output/highcharts)

glecharts](https://sciruby.github.io/daru-view/spec/dummy_nanoc/output/googlecharts)

now, other applications (Rails/Sinatra) you need to run it locally.


pdate to latest js library. Additional command line

 update to the current highcharts.js directly from http://code.highcharts.com/",  you can always run

rake highcharts:update

d it will be copied to your adapters/js/highcharts_js directory.

milarly for other libraries.

 update the all libraries Javascript file, run this command :

rake update_all


evelopment

r checking out the repo, run `bin/setup` to install dependencies. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

rally I prefer to use `bundle console` for testing few codes and experimenting the gem repo.
