JavaScript Gantt Features
PRO Edition of JS Gantt Library
Resource allocation
The PRO edition enables you to develop Gantt charts with efficient resource management capabilities. PRO features allow users to allocate resources to tasks and track the workload with the help of resource usage diagrams, histograms, and resource calendars.
Critical path analysis
Another essential PRO feature is the critical path calculation. It is a cornerstone in project management, which determines vital tasks and the minimum duration of the whole project. Tasks that can’t be postponed are highlighted in red.
Adding custom content on top of Gantt
In addition to various custom elements inside Gantt, you can display any custom content on top of the chart as well. In our example, an additional layer above Gantt contains an S-curve, which depicts the project progress.
