PRO Features Overview

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.

View sample

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.

What Customers Say

Truly Exceptional Products!

We searched high and low for a suite of components to make our lives much easier in developing our products, We initially had a need for a Gantt Chart and this one really stood out from the rest. I can tell you that after implementing it on 2 large products we are very impressed with the quality of this component as well as their other products.

Outstanding component

After reviewing many options for a Gantt component, we selected the one from DHTMLX. It is beautifully designed (appearance/UI) which was a key consideration for us, but really it's the full scope of features and capabilities that make it stand out. It has the flexibility for us to make it work exactly the way we need, and it has been a very simple process to integrate it and get it up and running.

Best choice for product development. Absolutely

It's stable. It's easy to setup, even if you don't have to much development experience. It's highly customizable. It's full of features out of the box (and if something missing, you can write your own addon to cover missing functionality). It's beautiful out of the box, which is not always the case for similar components. Workload functionality is included, which is not the case for such components.
