Easychart

A visual editor for the world's best web charting tool: [Highcharts] (http://www.highcharts.com/)

WHAT IS EASYCHART?

Easychart is a graphical user interface, built on top of the stunning Highcharts-javascript library.

It was born (somewhere in 2013) out of the need to make it possible for website-editors to embed and configure Highcharts in our websites in a more intuitive way than writing javascript code in the backend. So it has evolved from a sneaky textarea to a simple yet customizable user-interface where one can create a "Highcharts Options Object" (and thus a Highchart-chart) by pasting csv-data and clicking around.

Integration

HighCharts

Easychart is written as a vannila js application, very easy to integrate in your specific project or content management system. In fact, the Easychart-plugin isn't really made for standalone-use, it is made to shine in the backend of content management systems.

We've already built an [Easychart-module for Drupal] (https://www.drupal.org/project/easychart) which blends seamlessly with our Easychart-plugin. This module makes it possible to manage your charts in a convenient Drupal-manner. Even more, a chart only needs to be made once and can be reused in other nodes, views, panels... Not enough? It even has WYSIWYG-integration so it's possible to add charts through your texteditor.

The Easychart-plugin and -Drupal-module are free.

Attention [Highcharts] (http://www.highcharts.com/) is free for personal, school or non-profit projects under the Creative Commons Attribution - Non Commercial 3.0 License. For commercial and governmental websites and projects, you need to buy a license. (But they're absolutely worth every penny.) See [License and Pricing] (http://shop.highsoft.com/highcharts.html).

With Easychart we hope to make the beauty of Highcharts accessible to almost everyone. The people at [Highsoft] (http://www.highcharts.com/about) are (y)our true heroes, credit where credit is due.

Handsontables

If Handsontables is loaded before easycharts, it will use it automatically as data editor. Otherwise is it will fallback to a simple editable table.

options

You can pass on a options object to the easychart intialiser. The initialiser is best wrapped in a DOMContentLoaded wrapper.

document.addEventListener("DOMContentLoaded", function () {
    var options = {};
    new ec(options);
})

options.element

var containerNode = document.getElementById('container');
new ec({
    element: containerNode
});

options.templateTab

Toggle on and off the templates tab [default:true]

new ec({
    templateTab: true
});

options.dataTab

Toggle on and off the data tab [default:true]

new ec({
    dataTab: true
});

options.customiseTab

Toggle on and off the customise tab [default:true]

new ec({
    customiseTab: true
});

options.debuggerTab

Toggle on and off the debugger tab [default:false]

new ec({
    debuggerTab: true
});

options.data

var data = [
    [0,1,3],

]
new ec({

});

options.dataCSV

Pass a csv string with data.

var csvString = '1,2,3'
new ec({
    dataCSV: csvString
});

options.dataUrl

Setup

// install dependencies
npm install
// watch and build app
gulp watchify:app
// watch and build render app
gulp watchify:render
// production build the app
gulp build

Generate options file

The project also contains a small nodejs script that merges the customise with the definitions from the highcharts attributes dump file.

To run the generator:

// install dependencies
npm install
// run generator
npm run genOptions

Builds

App

App build is used when configuring a chart and is best used in a backend/logged in usecase, since it quite large and has loos dependencies like highlightjs and handsontables.

Render

Render build is used for converting raw data and configuration to an highcharts graph, this build is best used for displaying graphs build by easychart. The render build only has a limited set op options and api calls.

options:

  • data
  • dataUrl
  • config
  • presets
  • element

api:

  • setData
  • setDataUrl
  • setConfig
  • setPresets
