Charting

xChart is an XML language that can be used to generate all-purpose charts using XF Rendering Server 2008. In addition, the charts can be included in XSL-FO documents for the purpose of producing PDF reports.

Features at a glance

Supports XML as input.
Can produce Pie, Area, Bar, Spider, Scatter and Line charts. It is also able to render combinations of these types.
A chart can include XSL-FO and SVG elements. In the examples below, the legends are in fact embedded XSL-FO documents.
Produces PDF, GIF, JPEG, PNG, BMP and other formats.
Supports text and shape antialising.

How does it work

Having a generic XML document, developers must build a stylesheet that defines presentation rules. The process of combining the input XML and the style sheet is called XSLT(XSL Transformation) and must result in a xChart document. XF Rendering Server 2008 is able to process the xChart XML to produce GIF or JPEG graphics, suitable for on-screen viewing, as well as ready-to-print PDF documents.

For example, the same data can be used to render charts for your web site as well as PDF reports. The last example on this page shows a chart included in a PDF document. The same chart is the first example shown below.
