We very often develop a Gantt scheduling application for manufacturing companies. In these cases, our customers want to schedule orders (and their operations) and manage the machine utilizations by using Gantt charts. A machine utilization Gantt chart illustrates which operations are worked off at which machines at which time. In case that an order consists of many operations, links are used to let the planner better understand the depdencies. Typically, these links can, however, only be switched on or off for the complete view and all orders. If a company processes many orders simultaneously, displaying these links can result in a “visual chaos”. This blog post shows how - by using a trick - you can display only links of selected orders when working with our .NET Gantt chart control VARCHART XGantt.
In Gantt charts activities are often displayed in groups. This is done, for instance, in a "machine Gantt" which visualizes the machine load, and which differentiates machine groups and the respective machines. This is called double-staged grouping.
Groups in Gantt charts imply expanding and collapsing, depending on whether one wants to view the planning data in a broader perspective or in detail.
And this is exactly where conventional Gantt controls face issues: Normally, nodes are only displayed on one group level. How is it possible then to display nodes in a Gantt chart group either collapsed at the top level or expanded at the lowest level?
This new post from our Gantt tips and tricks blog series explains how you can visualize the nodes on the group level you want and how an individual group based arrangement of nodes enhances the information value of the Gantt chart representing your planning data.
