In the Graph node, you define the display of the signal displays and the trends.

You can define a title for each signal graph (trend) within a trend graph signal display. You can enter a title and determine the font, text and background color and alignment of the title line.

In the Height field you can set the height of the graph in pixels.

Dynamic visibility allows the complete signal to be controlled visibly or invisibly via a digital signal. This corresponds to the manual function, which can be activated with the monitor icon.

The color of a signal can be dynamic. It can be controlled by another signal. In the signal table of the graph properties, you can determine the signal for the dynamic colors (see figure above). This signal must be an analog signal between 0 and 15. There are 16 different colors available and the color signal selects one of them depending on its value. You can specify the 16 colors in the trend graph properties (see figure below).

The thickness of the signal can be firmly adjusted or can be controlled dynamically by another signal. For example, the curve can be visible or not visible for a certain state or the line width can be displayed wider.

In the column Style, the graph display with or without filling can be selected.

Graph properties of vector signals

If vector signals have been placed on the trend graph, the start and end zone options can also be set. A vector signal consists of a group of several individual signals which describe a so-called “zone”. If only part of the zone should be displayed, a begin zone and an end zone can be defined.

Example: Several signals measure the thickness of a strip in different zones across its width, and are summarized in a vector. For example, if you want to hide the edges of the strip, you can define the desired middle range via the begin and end zones.
