About Gantt Charts

In Oracle Analytics, you can use Gantt charts to visualize project or operation schedules and track the progress and duration of tasks or events.

Gantt charts use the vertical axis to list tasks or events and the horizontal axis to display time. Horizontal bars in the chart represent the duration of each task or event. Diamonds represent tasks or events with no end date in the data.

You can display two time ranges, or layers, in a Gantt chart. For example, you might want to compare the planned duration of the tasks in a project with the actual time it took to complete them.

You use additional columns to apply color or size to the bars in the visualization to represent things like task status and complexity, or resources used.

For example, this Gantt chart shows a project schedule with two layers of tasks. The thicker bars represent the actual task duration while the thinner bars represent the planned duration. The bar color represents the status of the tasks and the height of the bars represents how many resources are used by the tasks. The Testing task displays a diamond because it doesn't have a defined end date.

You can update the visualization properties to change the axis scales, labels, and position as well as configure the grid lines.

To view the data in a Gantt chart more clearly, use the Zoom In and Zoom Out controls on the visualization.
