Chart4.NET - Dynamic and Automatic Hierarchy/Organization Chart Control

Welcome to industry's most comprehensive and easy-configurable organization/hierarchy/tree chart control from OnlineUnifosys, that allows .NET developers to quickly build organization chart enabled applications and web pages. It is also useful to create hierarchy-chart based GUI applications. Hierarchy charts with unlimited nodes and levels can be easily created and navigated using automatic subcharts. It is Dynamic (data). It is Automatic (drawing).

What is hierarchy?

Hierarchy is the organizational relationship of items within a group. Groups can be that of people, components of any type of objects, networks or activities. Actually Onlineeverything is hierarchical. Hierarchy charts provide a quick overview of the groups and items together with its details and photos.

What is a hierarchy chart?

Hierarchy chart is a pictorial representation of hierarchy. Chart4.NET provides advanced formatting and easy configuration options to create highly effective organization charts. Hierarchy charts can dynamically obtain data from a wide variety of data sources including database, XML, treeview etc.

Create a hierarchy chart with a single line of code

Eventhough the organization chart control has a lot of customization settings, the default settings are sufficient most of the time. The only necessary part is to specify a treeview control in hpDataTree property or to specify the tree of nodes in hpDataTreeCollection property:

hierarchyWin1.hpDataTree = TreeView1;//System.Windows.Forms.TreeView object

hierarchyWeb1.hpDataTree = TreeView1;//System.Web.UI.WebControls.TreeView object

So it is really simple to get started, and to experiment the customizations.
Download the free Onlinehierarchy-chart designer sample project (no setup required) to experiment with chart control features.

Default brushes, fonts, layouts etc. are set for the control. If you want, you can change anything of them. There is separate bruhes (color+style/gradient) and fonts for title, text and tag. And there is a lot of optional features which can be enabled or disabled (zoom, preview, subcharts etc.). Please see the screenshots.
