Duration Units in Vue Gantt component

Duration units

In Gantt, the task’s duration value can be measured by the following duration units,

  • Day
  • Hour
  • Minute

In Gantt, we can define duration unit for whole project by using durationUnit property, when we defines the value for this property, this unit will be applied for all task which don’t has duration unit value. And each task in the project can be defined with different duration units and the duration unit of a task can be defined by the following ways,

  • Using taskFields.durationUnit property, to map the duration unit data source field.
  • Defining the duration unit value along with the duration field in the data source.
