Visualization Element: Bar Display
Symbol:

Category: Measurement Controls
The element displays the value of a variable.
Element properties
Are all element properties available?
All properties are available only after you select the Advanced option or the All categories filter in Properties.
Element name | Example: TipAssign individual names for elements so that they are found faster in the element list. |
Element Type | Bar Display |
Value | Variable (numeric data type) The value of the variable is displayed as a bar length. |
Center
The properties contain fixed values for the coordinates of the point of rotation. The rotation point is displayed in the editor as the TipYou can also change the values by dragging the | |
X | X-coordinate of the point of rotation |
Y | Y-coordinate of the point of rotation |
Absolute movement
The properties can be assigned to IEC variables for controlling the position of the element dynamically. The reference point is the upper left corner of the element. At runtime, the entire element is moved.
Movement | ||
X |
Increasing this value at runtime moves the element to the right. | |
Y |
Increasing this value at runtime moves the element downwards. | |
Rotation | Variable (numeric data type) for the angle of rotation (in degrees) Example: The midpoint of the element rotates at the Center point. This rotation point is shown as the At runtime, 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. | ![]() |
Interior rotation | Variable (numeric data type) for the angle of rotation (in degrees) Example: At runtime, 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 NoteIf 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. | ![]() |
Tip
You can combine the variables to a Unit conversion.
Tip
The X, Y, Rotation, and Interior rotation properties are supported by the "Client Animation" functionality.
Animation
Tip
These properties are available only when you have selected the Support client animations and overlay of native elements option in the Visualization Manager.
Animation duration | Variable for the duration (in milliseconds) in which the element runs an animation
. Animatable properties
The animated movement is executed when at least one value of an animatable property has changed. The movement then executed is not jerky, but is smooth within the specified animation duration. The visualization element travels to the specified position while rotating dynamically. The transitions are smooth. |
Move to foreground | Variable (
Example: |
Background
Image color | List box containing background colors NoteThis property depends on the style. For example, there are no heterochromatic background images for FlatStyle and Whitestyle. |
Own image |
|
Optimized drawing |
NoteDeactivating this option is sensible only in certain exceptional cases. |
Position
The position defines the location and size of the element in the visualization window. This is based on the Cartesian coordinate system. The origin is located in the upper left corner of the window. The positive horizontal X-axis runs to the right. The positive vertical Y-axis runs downwards.
X | The X-coordinate (in pixels) of the upper left corner of the element Example: |
Y | The Y-coordinate (in pixels) of the upper left corner of the element Example: |
Width | Specified in pixels Example: |
Height | Specified in pixels Example: |
Tip
You can change the values by dragging the box symbols to other positions in the editor.
Bar
Diagram type | Position of the scale
|
Orientation | . Orientation depending on the ratio of width to height of the bar display:
|
Running direction | Direction the values are increased . List box for Orientation Horizontal:
. List box for Orientation Vertical:
|
Optimum size for bar |
NoteThis property depends on the style. For this reason, it is not provided for FlatStyle or WhiteStyle. |
Scale
Scale start | Least value of the scale and therefore the lower limit of the value range for the element Example: TipIn the value field, click the |
Variable | Variable (integer data type) for the scale start Example: Declaration: |
Scale end | Greatest value of the scale and the upper limit of the value range for the element Example:
|
Variable | Variable (integer data type) for the scale end Example: Declaration: PROGRAM PLC_PRGVAR iScaleEnd : INT := 120; END_VAR |
Main scale | Distance between two values on the main scale Example: TipIn the value field, click the |
Variable | Variable (integer data type) for the spacing Example: |
Sub scale | Distance between two values on the fine scale You can hide the fine scale by setting the value to Example: TipIn the value field, click the |
Variable | Variable (integer data type) Contains the distance. Example: |
Scale line width | Specified in pixels Example: |
Scale color | Color of the tick marks
|
Scale in 3D |
NoteThis property depends on the style. Not available for FlatStyle. |
Element frame |
|
Label
Unit | Text which is displayed in the element Example: Display of units in m/s |
Font | Font for labels (example: scale numbering). Selection made from the list box or by clicking the |
Scale format (C syntax) | Values scaled in "printf" syntax Examples: |
Max. text width of labels | Optional value that defines the maximum width of the scale label The value is set automatically. TipChange this value only if the automatic adjustment does not actually yield the expected result. |
Text height of labels | Optional value that defines the maximum height of the scale label The value is set automatically. TipChange this value only if the automatic adjustment does not actually yield the expected result. |
Font color | Selection from the list box or by clicking the |
Positioning
Horizontal offset | Distance (in pixels) from the scale or bar to the horizontal element frame Used for achieving the exact position relative to the background image |
Vertical offset | Distance (in pixels) from the scale or bar to the vertical element frame Used for achieving the exact position relative to the background image |
Horizontal scaling | Horizontal division of the scale (in pixels) Used for achieving the exact positioning relative to the background image |
Vertical scaling | Vertical division of the scale (in pixels) Used for achieving the exact positioning relative to the background image |
Colors
Graph color | Color of the bar |
Bar background |
|
Frame color | Color that the frames are drawn |
Switch whole color |
|
Use gradient color for bar |
|
Color range markers | . The color areas can be separated from each other inside the bar with a vertical mark.
|
Color areas | |
Create new | A new color area is added. |
Delete | The color area is removed from the list. |
