Gantt Chart with Dates

Gannt chart is a variation on Bar chart commonly used to visualize project schedule. Each bar represents a task in the schedule with its start and end locations corresponding to the date/time of the item’s beginning and end.

Key implementation details

The only change needed to convert a regular bar chart with date-based values to a Gantt chart is changing its start values, so bars don’t sart on the category axis, but rather on a specific value. We achieve this by setting openValueXField on the ColumnSeries.
