By using the argument alignment multi-line texts can either be aligned to the left (alignment = left), in the center (alignment = center) or to the right (alignment = right). As the default, multi-line label texts are formatted flush left.

The 7th argument orientation makes it possible to turn texts in a desired direction. When entering an angle greater than zero, texts are turned clockwise; a negative angle turns them counter-clockwise. All angles are to be entered within a range of ±360 degrees; 0 degrees is horizontal (3 o'clock).

When setting a maximum width (maxWidth > 0), longer multi-line texts can be issued as continuous text with automatic word wraparound. The height of the text block can be controlled by the argument maxHeight. Texts which do not completely fit into the area predefined by maxWidth and maxHeight will be shortened according to the setting by the argument ellipsisPosition. Five options are available:

ellipsisPosition Truncation Ellipsis
0 end (No ellipsis)
1 begin ...text
2 middle text...text
3 end text... (Default)
4 begin + end ...text...

As the default, maxWidth =​ –1 and maxHeight =​ –1 are set, i.e. no width and height constraints and, thus, no automatic word wraparound support. An additional option is available for bar and Gantt charts. When maxWidth =​ –2 and/or maxHeight =​ –2, the width and/or height of the bars is used as limitation for the text blocks. This has proven advantageous, particularly for Gantt charts such as used for project management and date planners.
