FlowChartX is available in two editions - Standard and Professional. Advanced features that are expensive for us to develop usually end up in the Pro version. FlowChartX Pro includes all the functionality of the standard edition, plus:

• support for multi-level undo and redo
• clipboard operations: copy, cut and paste
• LayeredLayout automatic layout algorithm
• GridLayout automatic layout algorithm
• AnnealLayout automatic layout algorithm
• FractalLayout automatic layout algorithm
• Ruler control
• automatically route arrows to avoid crossing nodes
• container nodes that can hold other nodes
• hosting ActiveX controls in diagram nodes
• export or import Visio 2003 VDX files
• export SVG (Scalable Vector Graphics) files
• support for shape library plugins

There is a separate trial version for the Professional edition available here. Download it if you are interested in evaluating the features listed above. If you are not sure what is the edition of the demo you have, please check the name of the control's dll file; it should be called flowchartpro.dll for the Pro version.
