Visualization Element ‘Polygon’, ‘Polyline’, ‘Bézier curve’¶
Symbol:
Label: Basic
The elements polygon, polyline, and Bézier curve are the same element type. They can be converted into another type by changing the Element type property.
Elements can be dragged and dropped to the editor. The element is then drawn with five points: [0] to [4].
Other positions are added as follows: Move the mouse pointer over a corner point; the mouse pointer changes shape. Now if you press and hold Ctrl
and click the left mouse button, another point is created. You can delete a point by pressing and holding Shift
+Ctrl
and click the selected point.
As an alternative, you can select the element in the toolbox area and in the editor click multiple times. At the same time, a connecting line is drawn from one point to the other. End by double-clicking the element or right-clicking it one time.
Element properties
Element name | Optional. Tip: Assign individual names for elements so that they are found faster in the element list. Example: |

Element property ‘Position’
The following properties define the position of the corner points in the visualization window. These are based on the Cartesian coordinate system. The origin is located at the upper left corner of the window. The positive horizontal x-axis runs to the right. The positive vertical y-axis runs downwards.
Dots | [0]..[n]: Coordinates of the corner points Specified in pixels You can also change the values by dragging the box symbols ( |
Angle | Static angle of rotation (in degrees). Example: The element is displayed rotated in the editor. The point of rotation is the center of the element. A positive value rotates clockwise. Tip: You can change the value in the editor by focusing the element to the handle. When the cursor is displayed as a rotating arrow (1): Handle Note: If a dynamic angle of rotation is also configured in the property , then the static and dynamic angles of rotation are added in runtime mode. The static angle of rotation acts as an offset. |

Element property ‘Center’
The properties contain fixed values for the coordinates of the point of rotation. This point of rotation is shown as the symbol. The point is used as the center for rotating and scaling.
X | X-coordinate of the point of rotation |
Y | Y-coordinate of the point of rotation |
Note
You can also change the values by dragging the symbols ( ) to other positions in the editor.

Element property ‘Texts’
The properties contains character strings for labeling the element. The character string can also contain a placeholder with a format definition. In runtime mode, the placeholder is replaced by the current value in the specified format.
CODESYS accepts the specified texts automatically into the GlobalTextList text list. Therefore, these texts can be localized.
Text | Character string (without single straight quotation marks) for the labeling the element. Example: The variable that contains the current value for the placeholder is specified in the property . |
Tooltip | Character string (without single straight quotation marks) that is displayed as the tooltip of an element. Example: The variable that contains the current value for the placeholder is specified in the property . |

Element property ‘Text properties’
The properties contain fixed values for the text properties.
Horizontal alignment | Horizontal alignment of the text within the element. |
Vertical alignment | Vertical alignment of the text within the element. |
Text format | Definition for displaying texts that are too long
|
Font | Example: Default
|
Font color | Example: Black
|
Transparency | Whole number (value range from Example:
Please note: If the color is a style color and already has a transparency value, then this property is write-protected. |
Element property ‘Absolute movement’
The properties contain IEC variables for controlling the position of the element dynamically. The reference point is the upper left corner of the element. In runtime mode, the entire element is moved.
Movement | ||
X | Variable (numeric data type). Defines the X position (in pixels). Example: Increasing this value in runtime mode moves the element to the right. |
|
Y | Variable (numeric data type). Defines the Y position (in pixels). Example: Increasing this value in runtime mode moves the element downwards. |
|
Rotation | Variable (numeric data type). Defines the angle of rotation (in pixels). Example: The midpoint of the element rotates at the Center point. This rotation point is shown as the in runtime mode, the alignment of the element remains the same with respect to the coordinate system of the visualization. Increasing the value rotates the element to the right. |
|
Scaling | Variable (integer data type). Causes centric stretching. Example: The reference point is the Center property. The value |
|
Internal rotation | Variable (numeric data type). Defines the angle of rotation (in pixels). Example: In runtime mode, the element rotates about the point of rotation specified in Center according to the value of the variable. In addition, the alignment of the element rotates according to the coordinate system of the visualization. Increasing the value in the code rotates clockwise. The rotation point is shown as the Note: If a static angle of rotation is specified in the property , then the static angle of rotation is added to the variable angle of rotation (offset) when the visualization is executed. |
|
Use REAL values | Note: Only available if the device supports the use of REAL coordinates.
The option allows for the individual fine-tuning of drawing the element, for example for the visualization of a smoother rotation. Tip: If a horizontal or vertical line is drawn blurry on a specific visualization platform, then this can be corrected by an offset of 0.5px in the direction of the line thickness. |
Note
You can link the variables to a unit conversion.

Element property ‘Dynamic points’
Array of points | Variable ( The variable that is assigned to the property Number of points contains the number of array elements and therefore the number of corner points. Example: |
Number of points | Variable (integer data type): Contains the number of array elements and therefore the number of corner points for displaying the element. Example: In the example, the element has 24 points. This definition is necessary because the individual points are defined by a pointer and this does not allow control over the number of points. Note: In this way, it is possible to adapt the display of the element dynamically by updating the number of corner points. |
Element property ‘Text variables’
These properties are variables with contents that replace a format definition.
Text variable | Variable (data type compliant with the format definition). It contains what is printed instead of the format definition. Example: Note: The format definition is part of the text in the property .Note: If you specify a variable of type enumeration with text list support, then the name of the enumeration data type is added automatically in angle brackets after the variable name. Example: |
Tooltip variable | Variable (data type compliant with the format definition). It contains what is printed instead of the format definition. Example: Note: The format definition is part of the text in the property . |

Element property ‘Input configuration’
The properties contain the configurations for the user input when using the mouse or keyboard. A user input defines an event and one or more actions that are executed when an event occurs.
The Configure button opens the Input configuration dialog box for creating or modifying a user input. Configured user inputs are briefly listed below the events. They each include the action that is triggered and the setting in short form. Example: Execute ST code: |
|
OnDialogClosed | Input event: The user closes the dialog box. |
OnMouseClick | Input event: The user clicks the mouse button completely. The mouse button is clicked and released. |
OnMouseDown | Input event: The user clicks down on the mouse button. |
OnMouseEnter | Input event: The user drags the mouse pointer to the element. |
OnMouseLeave | Input event: The user drags the mouse pointer away from the element. |
OnMouseMove | Input event: The user moves the mouse pointer over the element area. |
OnMouseUp | Input event: The user releases the mouse button over the element area. |
