Highcharts Serverside Export
============================
The primary goal of the Highcharts Serverside Export framework (HSE) is to provide a java API for Highcharts including image generation capabilities.
Solution features :
* Java API corresponding to [Highcharts](http://www.highcharts.com) model (kept compatible with Highcharts model hierarchy and properties),
* Rhino-Apache Batik based renderer : java ChartOptions ==> Rhino ==> Highcharts ==> SVG ==> image (png, JPEG, etc...),
Usage
-----
You can use the framework to generate in java an image file out of a Highcharts chart.
* With Highcharts, you would generate a javascript chartOptions, which is shown in browser
* Here, you generate a java chartOptions (same hierarchy, same properties), which is converted in image stream (using Rhino, Highcharts and Batik)
Getting Help
------------
To start to use it, you need to know Highcharts API.
## Highcharts
* See [Highcharts](http://www.highcharts.com/)
* See [Highcharts API Reference](http://www.highcharts.com/ref/)
## Highcharts Serverside Export java doc
* See embeded java doc (./doc)
## Rhino
* See [Rhino](http://www.mozilla.org/rhino/)
## Batik SVG Toolkit
* See [Apache Batik SVG Toolkit](http://xmlgraphics.apache.org/batik/)
Quick Start
-----------
## A java sample : SimpleExport (test/examples/SimpleExport.java)
public static void main (String[] args) {
// This executable expects an export directory as input
File exportDirectory = new File (args [0]);
// ====================================================================
// ChartOptions creation
// ----------------------
// The createHighchartsDemoColumnBasic method describes the creation of
// a java chartOption. It is a java equivalent to javascript Highcharts sample
// (see http://highcharts.com/demo/column-basic)
ChartOptions chartOptions1 = SamplesFactory.getSingleton ().createColumnBasic ();
// ====================================================================
// Chart export
// ----------------
// Inputs :
// 1. chartOptions : the java ChartOptions to be exported,
// 2. exportFile : file to export to.
HighchartsExporter pngExporter = ExportType.png.createExporter ();
pngExporter.export (chartOptions1, null, new File (exportDirectory, "column-basic.png"));
...
}
* export directory
You can choose the export directory by changing the java line :
* windows : File exportDirectory = new File ("D:\\");
* linux : File exportDirectory = new File ("/home/myself/export-dir");
* ...
* SimpleExample shows several cases of charts export :
* from 'java' chartOptions (column-basic) to png file,
* from 'java' chartOptions (pie-chart) to png file,
* from 'java' chartOptions (time-data-with-irregular-intervals) to jpeg file,
* from 'json' chartOptions (column-basic) to png file,
* from 'java' chartOptions (column-basic) to json chartOptions (as a String).
* Please note that following trace do not mean a mistake :
log4j:WARN No appenders could be found for logger (org.one2team.highcharts.server.export.util.SVGHighchartsHelper).
log4j:WARN Please initialize the log4j system properly.
ERROR: The JPEG quality has not been specified. Use the default one: no compression
SamplesFactory contains three methods that generate equivalent of Highcharts demo gallery examples :
* SamplesFactory.createColumnBasic : [Basic column](http://highcharts.com/demo/column-basic)
* SamplesFactory.createPieChart : [Pie chart](http://highcharts.com/demo/pie-basic)
* SamplesFactory.createTimeDataWithIrregularIntervals : [Time data with irregular intervals](http://highcharts.com/demo/spline-irregular-time)
## Running the sample
* jars
All the dependencies files are provided in ./lib/
* Eclipse :
The framework is eclipse ready.
* open the project in eclipse,
* run SimpleExport
* other IDE
* open the project in your favorite IDE,
* declare all the ./lib jars as dependencies in your project,
* run SimpleExport
