Gantt Chart Tip - How To Make Interactions Intelligent

Posted by Kerstin Sieckmann on Jun 8, 2015 1:30:00 PM

A well-designed Gantt chart should not be overloaded with information while at the same time it has to provide the planner with every crucial detail needed for decision-making. This balancing act can be mastered by applying an intelligently-designed interaction function. In this context, interaction does not only mean shifting an operation by drag & drop. It is meant in a sense that the Gantt diagram provides context-sensitive decision support information during the drag & drop interactions.

We call this “target-oriented interaction”.

How does this look like? In our series of Gantt chart tips this blog post introduces a Gantt application and focuses on the issue of an interaction in Gantt charts. It presents three planning & controlling scenarios, and specific interaction functions for each of these scenarios.

Gantt Best Practice: How To Use The Timescale As Scrollbar

Posted by Frank Köhnen on Feb 18, 2015 2:00:00 PM

If you have a timescale in a Gantt chart spanning several years, but still want to be able to see every single day or even the hours in a day, you will soon find that the horizontal scrollbar becomes very sensitive. The smallest movement leads the timescale to shift several days into one or the other direction, even if smaller intervals are required as you look for a specific date and time. This behaviour can result in some unwanted user experiences for the planner working with your scheduling application.

This blog post belongs to a series of Gantt best practices that we regularly publish relating to our Gantt control VARCHART XGantt. This trick describes how to extend the mouse functionality to also use the timescale as scrollbar.

Special VARCHART Collections Now support IDisposable Interface

Posted by Klaus Ribbrock on Feb 10, 2015 11:30:00 AM

In case of intensive use, some types of VARCHART collections can lead to a significant rise in occupied storage place if they are not released quickly. The three automation objects VcNodeCollection, VcGroupCollection and VcLinkCollection in VARCHART XGantt now support the .NET Interface IDisposable and explicitely release unmanaged resources.

This blog post instructs developers how to correctly access the collections when using the Gantt component VARCHART XGantt in order to ensure a minimal use of storage place in their application to improve the performance of your Gantt application.

Gantt Chart Trick: How To Visualize Operations With Short Durations

Posted by Alfred Göhlich on Jan 28, 2015 1:30:00 PM

Does this sound familiar? You have to visualize plenty of operations with short durations and have to cover both a short-term and a long-term planning horizon with one view in your Gantt scheduling appplication? There are two options of how to display the time scale. You could choose between

  1. A very detailed time scale, offering the advantage of making the single operations clearly visible but, on the other hand only showing a very short period, thus losing the overview.
  2. A rough time scale offering a good overview of a longer period, while however affecting the accuracy of details.

In our series of Gantt chart tricks we describe how to create advanced planning and scheduling charts with our .NET Gantt control VARCHART XGantt. Read in this blog post how to enhance the time scale function to realize a magnifiying glass letting you keep track of the longer period while at the same time zooming into a selected time window to show every detail of the operations.

Top 5 Gantt Chart Blog Posts of 2014 And What To Expect In 2015

Posted by Martin Karlowitsch on Jan 14, 2015 9:30:00 AM

Does this sound familiar to you? Often, we are so busy with our day-to-day work, that we simply do not have sufficient time to follow and digest all the new content on the topics that we have to cover. So starting into 2015, we looked back into 2014 and analyzed what were the top posts about Gantt chart methodology, Gantt controls and visual scheduling in terms of page views, retweets and LinkedIn comments. These top 5 posts are summarized here with a link back to the original post - this should help you catching up with the most prominent Gantt-related content we provided last year.

Gantt Best Practice: Visualize Working Times in a Bar

Posted by Ulrich Kuck on Dec 18, 2014 11:11:00 AM

Sometimes a planner is not only interested in the timing and duration of an operation but he also wants to see the number of work packages needed by a resource to complete an operation. Our Gantt component VARCHART XGantt allows visualizing the individual working times of a resource in the operation bar in an optical appealing way. Read the following blog post to learn how this works.

Gantt Tip: Selective Visualization of Links in a Gantt Chart

Posted by André Pick on Nov 27, 2014 8:33:00 AM

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.

Gantt Chart Best Practice: Integrate a Shift Calendar into Timescale

Posted by Christin Scheewe on Sep 29, 2014 3:30:00 PM

The timescale is a key feature of a Gantt chart since this visualization technique focuses time-related planning data. In some cases however, planners have to view shifts and therefore need time units other than hours and/or minutes. Moreover, the respective scheduling applications require that the shifts are shown directly in the timescale. In this blog post we describe in form of a Gantt chart best practice sample how to use the “Shift Calendar” function of  VARCHART XGantt  to create a timescale with integrated shift visualization.
