Gantt Chart

A Gantt chart is a tool used to display the project progress and timelines. It uses bar graphs to visually represent the start and end times of tasks, making it suitable for long-term and multi-phase project planning. With a Gantt chart, you can easily understand the overall structure of a project, monitor the task progress, and make timely adjustments to plans in response to changes.

This section will show you how to add data and configure styles for Gantt charts.

**Table 4** Chart linkage settings
Parameter	Description
Fields to Bound	Select the fields to be bound first and then select the chart to be associated with them. You can select all charts on the dashboard.
Associated Charts	Set linked associated charts. You can select charts from the same dataset or different datasets. Follow bound field: When the bound field is set to A, the associated data tables filter data related to A.
