Can anyone indicate me to a framework of BI / OLAP or at least a Chart Engine, preferably open source, which properly integrate with MEAN.JS or MEAN.IO platform in SPA - Single Page Application architecture?
I know the keen.io. It is free in low transactional volume, but it is not open-source.
The Pentaho is a great BI tool, it's open-source, has RESTful Services and supports MongoDB, but your dashboard still employs Java on the server side and is one generation behind frameworks like Node.js and Angular.JS and they are only migrating now for jQuery and Bootstrap.
Thank you in advance for any contribution.
There is a amazing API, similar to jQuery in objective of manipulate DOM for you to compose graphic charts, named D3.JS - Data-Driven Documents d3js.org.
There is a chart engine named NVD3 nvd3.org, built on D3.JS, that allow you apply re-usable chart components in your Javascript applications.
There is a Angular.JS module named AngularJS-NVD3-directives http://cmaurer.github.io/angularjs-nvd3-directives/, that integrate the chart components of NVD3 into directives of Angular.JS, allowing use it natively in your Angular.JS applications.
You can integrate AngularJS-NVD3-directives components with Pentaho RESTful services via Mongoose accessing your MongoDB data to build dashboards and scoreboards control panels for your applications.
You still need to write code to integrate each of the components of a control panel as grid layout, themes, field projection and visibility, filter, sort, pivot tables and charts.
Today, the development process of control panels isn't straightforward, but you already have an open source solution good enough to design impressive applications.
