The following table lists the Data Arrays and describes the effect each one has on Gantt charts. Each data series requires the use of the X array and two Y array values including Y and Y1 to be charted. Adding values to the other arrays will not affect this chart, but filling the arrays with data could make it easier to switch to another chart type that does use those arrays:
| Property | Description |
|---|---|
| X | Holds the position on the X-axis. |
| Y | Holds the start value for the start time of the project. |
| Y1 | Holds the end value for the finish date of the project. |
| Y2 | No effect for Gantt charts. |
| Y3 | No effect for Gantt charts. |
