Benefit from the clear-cut and comprehensive display of tasks in the form of Gantt charts. No matter what application area you are in, Gantt charts can be an eye-catcher as well as an intuitive and useful planning tool for your users. For more than a decade VARCHART XGantt has been refined and is a proven component for many application areas, such as production planning and control, logistics, project management, service management as well as scheduling and dispatching.


Main Features Include:

Bars

Represent your data, dates, durations, and degrees of completion graphically by bars, symbols or bitmaps that may overlap and can be labelled. Use different bar shapes and colors based on your data by creating and applying filters and assignment tables.

Grouped Layout

Arrange your activities or orders by grouping them based on your own data field(s). Even multi-level grouping is a snap. Summarize groups using group titles and summary bars. Sort groups and their activities by any criteria. Arrange the activities or orders in a group, together with their annotations, in one line in order to save room.

Hierarchical Layout

Use VARCHART XGantt's hierarchical layout option to display activities/orders using a structured code field from your data. Levels are automatically indented, and can be expanded/collapsed with a simple click of the mouse.

Calendar Grid

Visualise non-working intervals with VARCHART XGantt's powerful and unique calendar grid. A different calendar can even be assigned for each group. A special calendar also can be assigned to each activity.

TimeScale

Specify a time scale tailored to your specific requirements. The time units of the timescale can vary between seconds and years. Several different ribbons can be displayed on top of each other. Annotate the ribbons with month or day names in any language. Save room by collapsing nonworking calendar intervals e.g. the third shift for a two-shift operation.

Table

Configure the columns of the table to your needs. Use assignment tables and filters to assign various backgrounds, fonts, and colors based on your data.

Histogram

Graphical display resource loading utilization in a histogram that adapts automatically to your current planning situation. Quickly display current load against actual availability. Overloads and subloads can be shown in several different ways. Different capacities can be graphically displayed all at once in several histograms, or by stacked curves in different colors/patterns in the same histogram.

Resource Scheduling

This module is offered for resource scheduling which will improve the efficiency of your planning process. Automatically it plans orders or tasks taking resources, work in processes well as delivery dates into account. Two optimization strategies are supported: “as soon as possible” for fast delivery and “as late as possible” for low stock.

Intuitive User Interaction for Adjustment of the Visualization

Create powerful and intuitive interactions that allow your customers to adapt the visualization to their needs without editing the data.

  • Display tooltip texts from the application data
  • Interactively move the date line or the timenow line
  • Set and interactively adjust diagram sections for the table, the Gantt graph and the histogram
  • Scroll diagram sections independently
  • Enlarge diagram sections continuously

Data Editing

Give your customers the ability to edit their data quickly and easily, while at the same time controlling which fields can be changed and which are "readonly". As the developer, you can take advantage of the many events provided by VARCHART XGantt to react to each user action as you deem appropriate. This gives you more power than most other Gantt products do to interact with the user.

  • Move activities or tasks by dragging them with the mouse
  • Change the dates of one or a selection of activities/tasks by moving them horizontally
  • Move activities vertically between groups, for example a task to a different machine
  • Move activities or tasks via OLE Drag & Drop into to a different diagram, even of a different application
  • Create or delete activities/tasks or links
  • Open a Data Edit dialog via double-click

In-place editing of data in the fields of the table. You may insert a combo-box or a date picker of your own into the table cells.

Printing and Print Preview

Offer your customers extraordinary printing functionality. Let them present their planning results on paper, or online, with polish and professionalism. VARCHART XGantt provides full Print Preview functionality and gives you control over all kinds of print layout features:

  • which parts of the diagram are to be repeated on each page
  • the paper format (size, margins...)
  • how to fit the diagram on the most efficient number of pages
  • how to export a diagram

Data Interface to VARCHART XGantt

The data exchange between VARCHART XGantt and your application is performed via file or via the application programming interface. You can supply the data as a complete record or field by field. Both, the data table for representing activities and the data table for representing links can have an unlimited number of fields. Datatypes for the data fields can be easily defined on the property page.

Property Pages

The property pages reduce dramatically the amount of code you need to write. You can use property pages for DataDefinition, Node, Sorting, Layers, Table, Title/Legend, Links, TimeScale, Histogram, Time Schedule and General Settings.

Excellent Runtime Behavior

Even with large datasets, your customers will enjoy excellent runtime performance. In close cooperation with our clients tests have been run over long times. Our clients report that VARCHART XGantt still performs well with 20,000 or more records loaded, during the initial built-up of the diagram as well as when working with it interactively.

Language Support

The product documentation is available in English and German. In development mode, VARCHART XGantt adapts to the language of the container (English or German). In runtime mode, the predefinded languages are English and German but each text item can be replaced by a term of your choice in any language. Unicode Characters are also supported.


Support

The Annual Maintenance and Support Service includes, Support hotline, detailed expert advice to questions of application, quick fixes of possible bugs in the software, upgrade to a new VARCHART XGantt release for development and runtime versions for a one year period.
