Gantt components

Gantt components summarize data by displaying it in a Gantt chart. The Gantt chart illustrates the start and end dates retrieved from your data source. Like the tree component, you can summarize fields in a hierarchy from your data source and visualize them in terms of start and end segments shown in the Gantt chart.

Gantt components are dependent on a start- and end-date field from your data source, so they may not be suitable for all forms of data. Gantt charts work best for tasks that have start and end dates, where the chart can display the duration of the task.

As with the other components, you set up the Gantt component with properties for the component and for the series. Currently, the Gantt component can have only one defined series.

Like the tree component, you can use the Gantt component to break down data from a single field into a hierarchy. Where a data field contains a hierarchy structure (such as First.Second.Third), the Gantt component can split this into separate start- and end-date values and show them on the Gantt chart as separate segments.

Additionally, you can select to display fields in columns that are separate from the hierarchy and that enhance the Gantt chart detail. See the example below. 

The display interval is shown by the two timelines that appear at the top of the Gantt chart. The display interval is calculated from data returned from the database (the earliest start-date value and the latest end-date value).

One timeline is a subdivision of the other, such as day, hour as seen below. The timelines are chosen based on display interval and the available space for labels.

Zoom in and out by clicking the + and – icons on the title bar. Additionally, you can zoom out by clicking the timeline shown below.

Gantt-component series

Follow the next procedure to define a Gantt-component series. Currently, the Gantt component can have only one defined series.
