Each type of graphical element has a separate tab showing the properties of the element. You can change the properties on these tabs.

Note the following characteristic features of the different graphical elements:

▪Each graphical element is defined by position and direction coordinates.

▪All elements are defined by start coordinates, but only arrows and lines are defined also by end coordinates.

▪Texts are defined only by start coordinates.

▪Rectangles or ellipses are defined by their height and width (relative coordinates beginning at the starting point).

▪The units of the coordinates depend on the assignment of the graphical element.

▪As already mentioned, the fixed axes are represented in a value range between 0 and 1000.

▪If the x-axis is not fixed, its value range represents the number of seconds beginning at a fixed start date.

▪Apart from this, an individual name can be allocated to each graphical element (in the Name of <element> box at the lower window border), so that it is easier to identify it later (for example in the list of graphical elements).

For each graphical element, you can set in the Style tab

▪the line appearance via

▪line style,

▪line colour and

▪line width

and

▪the fill mode via

▪fill colour and

▪fill pattern

.

The start date is specified in the luqs.ini initialisation file.

Working with graphical elements comprises these steps:

▪Inserting/editing a text element

▪Inserting/editing lines, rectangles, ellipses and arrows
