daru-view's Issues

[Rails] Daru, Highcharts, etc gems are not automatically loaded while including `daru-view` in Rails Gemfile

Before Daru wasn't included:

lokeshh:~/workspace/daru_rails (master) $ rails s -b $IP -p $PORT

<...>

After including Daru I got errors like lazy_high_charts not found. I'm wondering why aren't the included automatically.

Add #to_html method

As per discussion on SciRuby/daru#405, I think it'd be apt for the the to_html to be added to daru-view rather than in daru or daru-io. Please mirror the changes caused by SciRuby/daru#366 here. 😄

However, if further discussions on the issue tracker end up in a different conclusion, feel free to close this issue. I'm temporarily closing SciRuby/daru-io#39.

Fix generate_html method in googlecharts.rb

Wrong argument plots has been passed as the argument in the generate_body method here: https://github.com/SciRuby/daru-view/blob/master/lib/daru/view/adapters/googlecharts.rb#L77
Also, the HTML of the chart contains only the div part, so we need to create another template to include the initial_script also.

Improve code quality

Just go through the files and check if there is any rubocop disabled comment. Try to remove it and fix it.

HighChart generating chart body part in html

In main LazyHighCharts gem the html code generated using high_charts method contains var onload = window.onload; , So this script can't show charts in iruby. I have removed onload var and used the main script to generate body part of the chart (modification in lib/adapters/highcarts/layout_helper_iruby.rb) . But there must be a html code that works in both webpage as well as iruby notebook. I tried few modifications but it was not working on both.

Examples to be added for new features, in demo apps

We have demo_daru-view repo where we maintain our examples to demonstrate the features of daru-view and how we can use daru-view in different Ruby web frameworks (Rails/ Sinatra / Nanoc / Hanami).

Since we have added new features in this GSoC 2018 period we should update our demo apps accordingly.
Some real world examples (simple to advance) will be appreciated.

Remove the css file present in adapter/highcharts/css folder

This css file is already shifted to vendor/assest folder.

So it should be removed. @Prakriti-nith, am I correct?

Remove executables from gem specification

Due to this line in .gemspec:

 spec.executables   = spec.files.grep(%r{^bin/}) { |f| File.basename(f) }

...and to fact that bin contains executables of rake, thor, pry, rails (why?..), when `daru-view is installed, your versions of this executables replace the system ones. That should be fixed ASAP, it is a huge problem.

Nyaplot library generating model of the chart wrongly

Nyaplot library is working fine in IRuby notebook and generated the correct div part in IRuby . But in Web application Rails it is just showing the box not the charts in it. I hope JS files are loaded properly and I have checked it , it is fine.

Problem is generate_body which is generating the model of the chart slightly wrong. (It is adding the property also in the div hash, which must not be added).

Download chart button for highcharts library

Download button will be automatically added in right corner of the chart , when modules/exporting.js is added in LazyHighCharts.init_script and LazyHighCharts.init_iruby method.

Using the button we can download the charts as image/pdf.

Right now I get some problem in iruby notebook , when I try to add all dependent JS.

Issue with Arrow and Bar Formatters

Out of these six formatters, Arrow and Bar are causing some issues and rest are working fine. Bar formatter is working correctly in rails but in IRuby notebook it generates weird bars. See examples. Arrow formatter is neither generating arrows in nbviewer (working fine in localhost) nor in rails.

3 D plotting

Original : SciRuby/daru#154

• nyaplot 3d plotting

• highcharts 3d plotting : 3d pie chart example | just need to add options3d: {enabled: true,} options

• google charts 3d plotting : 3d pie chart example | just add is3D: true options

Add examples (GIF or Small videos) in README

There are many examples present in IRuby notebook and web app and here. We must have some interesting examples in README as well.

Google charts JS won't work offline

I have added google charts dependent JS loader.js and google_visualr.js in js folder. But these files have some internal internet dependencies.

See these line : https://github.com/Shekharrajak/daru-view/blob/master/lib/daru/view/adapters/js/googlecharts_js/google_visualr.js#L6

you can search https in the file. These may have some way to use it offline by loading the all the files.

(Note : google charts is created to be used as online and downloading the JS file is not recommended in google charts tool website as well)

[Rails] Where to add the dependent JS files?

From the README:

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

Could you mention specifically where this line needs to be added?

Highcharts and data_tables: html table as data source. Not working for iruby notebook

When we try to plot chart using html table generated from daru DataFrame or Vector, it works fine for web apps but it is not working in iruby notebook.

Refer PR : #38

Strange error Daru::Vector#plot undefined

Refer : #28 (comment)

For library nyaplot . Which worked fine in spec/dummy_iruby/Nyaplot_basic iruby notebook example.
It displayed this :

daru is fetched from sciruby/daru github repo and the above example works fine in console and dummy_rails app.

Reduce the size of the gem

We can see the gem size here : https://rubygems.org/gems/daru-view

Looks like our dummy_iruby notebook examples and js files increasing the gem size.But

• we should have all the features demo in iruby notebook.
• we should have dependent js files present in source code, so that it can work offline.

Is there anything else that causes, this much size ?

Error When Using Highcharts / Googlecharts

Hi,
when I try to use another plotting library other than the default I get an error.

Example:

require 'daru/view'

Daru::View.plotting_library = :googlecharts

df = Daru::DataFrame.new(
  {'Names' => %w(A B C), 'Data' => [2,3,5]}
)
  
Daru::View::Plot.new(df, {type: :bar, x: 'Names', y: 'Data'})

The error is:

NoMethodError
(undefined method `access_row_tuples_by_indexs' for #<Daru::DataFrame:0x00005598eae589f8>)

I'm using:

• Daru 0.2.1
• Daru-View 0.2.4
• Ruby 2.5

[DataTables]: Need to change require path

If issue: Shekharrajak/daru-data_tables#24 is done , then related changes has to be done in daru-view/datatables

[GoogleCharts] Updating of jsapi causes error in GoogleCharts

Updating the jsapi is causing error in the formation of GoogleCharts. (Refer this comment). For now, I have commented out that portion in this commit.

Fix rubocop error Style/MixinUsage in plot_list.rb

IRuby.html method was not working in Daru module as Daru already has a module IRuby in it. So, to make this work, I have included IRuby::Utils module at the top level here which causes this rubocop offence. Need to find some other way out.

Don't use CDN for getting JS assets

I think you're going to do this later, but keep this open until you do so.

Use the rake tasks that you had specified in your proposal.

Post GSoC: cleanup, refactoring, docs

First of all: I need to apologize for my insufficient participation in your work during summer.
Being one of initial proposal authors and SciRuby's dedicated code qulaity mentor, I've should provide you with much more help and suggestions. And I'd definitely do that, if not for the fact that I've fighted with severe clinical depression this summer.

But now I feel like being back to life (as you probably 've noticed by much more of dumb suggestions and discussions!) and are excited by the project. Yet I have a lot of suggestions on small things, and on how to make project more accessible to newcomers (e.g. docs and tutorials).

As 3 days before GSoC end is a bit late for those changes, I'd like to work together on the project cleanup and enchancement after GSoC would be finished and the dust will settle. (Of course, this means that we are gratefully accepting your summer work!)

If you are willing to work on a project after GSoC (which I am really hoping you are, but of course can't force or even ask you, if your plans differ), let's make this issue a "communication hub" for those further encancements?

[Nyaplot] Loading http over https

This doesn't belong here but writing it down so that we don't forget it.

Plotting using nyaplot over https doesn't work. One need to explicitly click on "Load unsafe" scripts in Google Chrome to make it work.

Highcharts IRuby notebook : load dependent JS

Dependent JS files :

• Initial

<script type="text/javascript" src="http://code.highcharts.com/highcharts.js"></script>

• for 3d plotting

<script src="https://code.highcharts.com/highcharts-3d.js"> </script>

• data.js dependencies when load data from html table/csv

<script src="https://code.highcharts.com/modules/data.js"></script>

• exporting download button at the right corner of the chart

<script src="https://code.highcharts.com/modules/exporting.js"></script>

• area range chart, bubble chart, bubble-3d chart type dependency

<script src="https://code.highcharts.com/highcharts-more.js"></script>

• for drilldown

<script src="https://code.highcharts.com/modules/drilldown.js"> </script>

There are many other JS files present but I think above these are enough.

Travis is failing

access_row_tuples_by_indexs is removed from the daru/dataframe.rb. Which was used in daru-view.

Refer : https://travis-ci.org/SciRuby/daru-view/jobs/398889551#L3671 , #93 (comment) ,
SciRuby/daru#454

Update JS files for the libraries

Developers can update the js files using these command in the repo:

rake library_name:update

e.g. rake highcharts:update

To update all the JS files : rake update_all

But how user will update it (who have installed the gem from the source or using gem install) ?

Probably we can have CLI and using command daur-view update_js library_name user can update the particular js . I like the way Thor gem works. But there is some other good Command Line Interface Gems as well.

Download tag for integrating with daru-io Exporters

Integrating daru-io Exporters manually each time with respond_to blocks in the controller of the Rails app has been done in SciRuby/daru-io#40. However, I think it'd be better for users to have a <%= download(@df) %> tag which will do the same for the user.

Improve the coverage report

When we run the rspec; using simpleCov we get the coverage report . Try to improve it as much as possible.

We just need more test cases written in spec folder for all the adapters and files.

Visualize multiple Daru::DataFrames and Daru::Vector in a single HighChart

As HighCharts supports multiple series in a single chart, we can add a feature to visualize multiple Daru::DataFrame and Daru::Vector in a single chart (Need to think how a user will provide the data - may be in the series format or some other).

daru_chart and daru_table

daru_chart and daru_table helper methods for rails app is already defined in #55 . We need similar helper methods for Sinatra and Nanoc app.

Original discussion : Shekharrajak/daru_examples_io_view_rails#12

Import data from google spreadsheets in google charts

Add a feature to retrieve data from Google spreadsheets and drawing the chart using that data.

Highcharts feature : Highstock must be added.

Currently highcharts.js and highcharts-3d.js is used in plotting. But there is highstock that has dependencies highstock.js.

Issue with exporting HighCharts in IRuby notebook

Exporting in web frameworks is completely offline. In IRuby notebook, offline-export supports only the exporting to png, jpeg and SVG format. Export to PDF is not working (not even through the exporting button in highchart). So, online exporting is done in IRuby notebook.
Now, there is a problem in online exporting that if we run-all all the cells of IRuby notebook then only the last chart will be exported. Individually, running the cells works fine.
So, either we need to find a way to export HighChart to PDF format when offline exporting is done or we should resolve the bug in online exporting.

Unable to install daru-view on my local computer

Gemfile has the following contents:

gem 'daru', path: '/Users/shekharrajak/Documents/gsoc17/daru'
gem 'nyaplot', path: '/Users/shekharrajak/Documents/gsoc17/nyaplot'

which doesn't enable me to install daru-view and try it out.

Update the link in description of the daru-view

Need to change https://shekharrajak.github.io/daru-view/ to https://sciruby.github.io/daru-view/

Google charts features

google Datatable have lots of features . But in google_visualr all the methods are not defined.
May be google charts is updated or added new methods/features. (Also google_visualr is not maintained for long). There may be different google chart gem that is better than this. All we can have some good methods in daru-view that can handle most of the methods.

Add more examples

These are many things we can do using Highcharts, GoogleCharts, Nyaplot, DataTables. I tried to add most of the basic examples in iruby notebook/rails/sinatra/nanoc web application in spec folder.

But there are many advance examples we can show for the highcharts, that must be added in iruby notebook spec/dummy_iruby

few are present here (for highcharts) : https://www.highcharts.com/community/charts/

Add proper dependencies

1. All these dependencies should ideally reside in daru-view gemspec so user just have to use gem 'daru-view'

2. There are other gems like 'datatables' that daru-view complain about while working. Those should be included in daru-view gemspec.

GoogleCharts feature: Toolbars can be added

Toolbar enables the user to export the underlying data into a CSV file or an HTML table. This works only when the data is given as the URL of the spreadsheet.

Testcases for Rails Helper methods daru_chart, daru_table

Refer #119 discussion

Highcharts in IRuby notebook works properly when it is saved

When we plot using HighCharts in daru-view in iruby notebook, it loads the dependent JS files properly but not able to display it in output cell (shows nothing).

But when we save the notebook file, and run the downloaded html file or other format it shows in chart properly in output cell.
