Description

The GanttChart() function serves to graphically organize time-dependent tasks, such as for project management. This type of chart was used for the first time in 1917 by Henry L. Gantt. Each task is defined by entering at least two values in ChartData() ; the first value defines the beginning of a task, the second value the end. By defining more than two values per series, a task can be divided into several partial tasks.

The 1st argument appearanceConstants makes it possible to rotate the chart 90 degrees (appearanceConstants = horizontal) and add shadow (appearanceConstants = shadow) and labels (appearanceConstants = label) to the bars. All options can be combined by using a plus sign "+".

The fills, borders and shadows can be varied by using the style functions FillColorScheme() , FillStyle() , PictureStyle() , BorderColorScheme() , BorderStyle() and ShadowStyle() and the labels by using the 4 style functions LabelTexts() , LabelTexts() , LabelBackground() and LabelOptions() .

By using the 2nd argument categoryGap, the space between the bars can be controlled. The argument categoryGap should be entered in percent of the bar width. As the default, the space between two bars is exactly one bar width, i.e. categoryGap =​ 100. For a categoryGap less than 100 the space is smaller and the bars wider; for a categoryGap greater than 100 the space is bigger and the bars narrower.
