The
Exontrol's ExGantt component is our approach to create timeline charts (also
known as Gantt charts). Gantt chart is a time-phased graphic display of
activity durations. Activities are listed with other tabular information on
the left side with time intervals over the bars. Activity durations are shown
in the form of horizontal bars. The Gantt object supports the following
