Gantt Chart Tips&Tricks: How to design a stylish tooltip

Posted by Alfred Göhlich on Apr 23, 2018 4:37:39 PM

Gantt charts visualize tasks, resources or capacities along a timeline and so provide an optimum overview for planners. When designing them, one should keep in mind to directly show information that is essential for the planner so that he can quickly recognize planning conflicts and intervene. Showing too much information might jeopardize the clarity. That is why a tooltip is a good way of showing important data only if needed. What is true for Gantt charts also applies to tooltips: information has to be perceived quickly, meaning that it has to be presented in a clearly sorted and arranged way. This step-by-step guide shows users of our Gantt component VARCHART XGantt how to design a clearly arranged tooltip.

Three Steps to Add a Comfortable Sorting Option to Grouped Gantt Charts

Posted by Alfred Göhlich on Jan 31, 2017 3:52:00 PM

Most people are used to a comfortable sorting option, like, e.g. in the Windows Explorer: Clicking the table header of a column will sort the files in in ascending or descending order, this being indicated by an arrowhead pointing upwards or downwards shown in the table header.

Wouldn't it be nice if you could use this functionality also in XGantt? In my blog post I'm going to show you how this is done in three easy steps and with little programming effort.

So, let's take a first look into calendars and how to mark workfree periods within activities.
