The primary goal of the Highcharts Serverside Export framework (HSE) is to provide a java API for Highcharts including image generation capabilities.
Solution features :
You can use the framework to generate in java an image file out of a Highcharts chart.
To start to use it, you need to know Highcharts API.
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"));
...
}
