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.
VARCHART XGantt is a powerful Gantt control (.NET and ActiveX edition) enabling you to create intelligent Gantt charts with little effort. Recently, one of our customers contacted us having a quite complex problem which our support could help to solve. As I’m sure that other developers working with VARCHART XGantt will also be interested in the approach we came up with I decided to give you a brief outline of the problem and its solution .
The approach involves interactively swapping tasks via the table and, as a consequence, adjusting the order in which they have to be processed.
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.
Two weeks ago, I started my series of blogs about the new version (5.1) of VARCHART XGantt by describing the new graphical features of our Gantt chart control. The release notes of this new version can be found here.
Here comes #2 of my series, where I'd like to give you some insights about what we've come up with concerning the snap tools making positioning objects easier.
We’ve come up with so much new features that introducing them all at once would go beyond the scope of one blog post. So I decided to split my description of what's new in the Gantt chart control into a series of blog posts, the first dealing with some great new graphical features.
This blog post addresses software developers building visual scheduling applications or considering to develop a graphical planning board with our .NET Gantt chart control VARCHART XGantt. It shows how you can use the recently introduced "InInteraction Events" functionality to customize the display of the duration in the tooltip (InfoWindow) during the drag & drop interaction. This post does not only give a step-by-step explanation of how to achieve this, but also provides the required code.
We assume that you closely followed our 'getting started with VARCHART XGantt' blog post series. If you did so, and if you applied your new knowledge to your Gantt scheduling application, this application should have become more and more powerful with every post of this series.
Now, that we covered many aspects of visualizing data, it is about time to also have a look at how to change data: This is, because the ultimate value of a Gantt chart is unleashed when you allow intelligent drag & drop interactions. This new blog post will show you some essential ways of user interactions. By the way: we regard user interactions as decisive when building visual scheduling applications and hence put them into the core of the the past release of our .NET Gantt control VARCHART XGantt and will further enhance them with the upcoming release end of June 2015.
This is blog #6 of our getting started with VARCHART XGantt series. If you followed all steps from the previous blog posts, you should have developed a pretty impressing Gantt chart application by now.
After we discussed the usage of layers and filters in the .NET Gantt control last time, we now focus on another area which will make your Gantt more meaningful to your users both from a 'look' but also from a 'feel' (i.e. the user interaction with the data) point of view. So, let's take a first look into calendars and how to mark workfree periods within activities.
