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.
Complete this procedure in either the Dashboard or Document Designer. This procedure assumes content from one of your data sources is already open in the details pane and displayed in a Gantt component format.
To edit components in a saved dashboard, you must first click the icon.
1.In the title bar of the Gantt component you want to edit, click the icon and select Component.
2.The Gantt Component dialog displays the following options:
•Title: Title for the Gantt component as it appears in the details pane.
•Series: Name of the series defined for the component. Currently, the Gantt component can have only one defined series. The Gantt Component Series dialog explains how to interact with any one series. For details, see the section below.
•Sort: Sort order for the Gantt chart. If you select a date sort order, it affects the order of the chart segments.
•Show task label: Select so that each Gantt chart segment shows its associated field value. Clear this option to turn off the field value display.
•Show duration label: Select so that each Gantt chart segment shows the task duration. If the task has sub-tasks, it's composed and the duration label is drawn on the segment graphic. If the task is not composed, the duration label is shown after the segment graphic. Clear this option to turn off duration labels.
•Hide start/end date columns: Select to hide the start- and end-date columns. By default, these columns are shown. The grid appears to the left of the Gantt chart.
•Highlight weekends: Weekends are highlighted by default. Clear this option to remove the highlighting effect on weekends.
•Show title summary: Xtraction creates a title summary of what the component does, along with your own title. If you clear this option, the default summary is removed. For example, the title "Incidents (Last Month)" becomes just "Incidents."
•Show collapsed: Select if you want the chart segments collapsed by default.
•Enter explanatory text directly into the blank area, which will display when your mouse hovers over the notes icon for the component. If Show notes is selected for an export, these notes are included in that component export.
Follow the next procedure to define a Gantt-component series. Currently, the Gantt component can have only one defined series.
3.In the Gantt Component dialog > General tab > Series area, double-click an entry.
4.The Gantt Component Series dialog displays with the details for that series.
•Title: Title for the Gantt series.
•Name: This field isn't required for Gantt components. Ignore.
•Data source: Data source used for this series.
•Start date field: Select a date field from the drop-down list to represent the start date of a segment on the Gantt chart.
•End date field: Select a date field from the drop-down list to represent the end date of a segment on the Gantt chart.
•Fields: The fields on which the start and end dates are to be summarized. Right-click in the Fields area and select Add field. Drag and drop the fields you want to include into the Selected Fields area and click OK.
•Columns: Additional details from the summarized field data to be shown as columns on the data grid. Right-click in the Columns area and select Add field. Drag and drop the fields you want to include into the Selected Fields area and click OK.
•Color: Color to use for the Gantt chart segments.
•A text description and color for the segments. Right-click in the columns area and select Add color to select a field, enter a data value (so the color will highlight the segment on the Gantt chart when the data contains this value), and color.
•Indicator lines tab
•Indicator lines to be shown on the Gantt chart as specific dates and times. You can give indicator lines a specific color. Right-click in the columns area and select Add indicator lines to set the options.
•Criteria used to filter the data from the data source. Right-click in the blank area and select to create filter or open a saved one.
