 | A Gantt chart is a type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the individual tasks within a project. |

Dataset
The gantt chart supports Custom Data model only.
It has the following Source Data Bindings:
Binding | Expected Value Type | Description |
Series | String | Textual name of the data series. Series are usually used to indicate project names in the multi-project charts. |
Description | String | Description of the task. Tasks are displayed along the domain axis. If one series contains several tasks with the same description, they will be displayed on the chart as several bars (subtasks) corresponding to one task. |
Start Date | Date or Number | Task start timestamp. Numeric values are converted to dates by treating them as number of milliseconds since the January 1, 1970. |
End Date | Date or Number | Task end timestamp. |
Percent Complete | Number | Task completion percentage. |
