Recently the ADF Special Interest Group at AMIS organized an ADF DVT Speed Date. During this speed date, six ADF specialists from our team presented their favorite Data Visualization Component from the DVT library. In a series of blog posts we share the information with a broader audience. In this post you get introduced to the Hierarchy Viewer – which was my own date for this party.

Introduction : The Hierarchy Viewer

A Hierarchy viewer is typically used to display hierarchical data. Examples of this are for instance a tree of life or a mindmap or even a family tree.

The ADF hierarchy viewer consists of several ADF components.

  • dvt:hierarchyViewer : This element wraps the dvt:node and the dvt:link elements
  • dvt:node : The dvt:node element supports the use of one or more f:facet elements that display content at different zoom levels (100%, 75%, 50%, and 25%).
  • dvt:link : connects one node with another node
  • dvt:panelCard : The panel card element provides a method to dynamically switch between multiple sets of content referenced by a node element using animation by, for example, horizontally sliding the content or flipping a node over.

Recently the ADF Special Interest Group at AMIS organized an ADF DVT Speed Date. During this speed date, six ADF specialists from our team presented their favorite Data Visualization Component from the DVT library. In a series of blog posts we share the information with a broader audience. In this post you get introduced to Gantt Charts – which was my own date for this party.

ADF DVT Gantt Chart – Introduction

The probably most distinguishing feature of any Gantt Chart is the horizontal time axis. Gantt Charts are used to present data against time.

Gantt Charts were invented in the 1910s by Henry Gantt (hence the name) – although a Polish engineer probably beat him to it but forgot to blog about it (http://en.wikipedia.org/wiki/Gantt_chart). They were used initially for presenting Project Schedules – showing tasks with their start time and end time and their dependencies. The essence of many modern project management tools is in fact a Gantt Chart – frequently an interactive one.

ADF DVT provides this project- and task overview in a Gantt format. Two additional Gantt Charts are provided as well:
