Visualization Element: Date Range Picker

Symbol:

Category: Date/Time Controls

The element provides the capability of selecting the date and time range of a saved data set. The element is used with the Trend visualization element.

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: `DateTrend1` Tip Assign individual names for elements so that they are found faster in the element list.
Element Type	Date Range Picker

Show frame	: The visualization element is drawn with a frame.
Resolution	Resolution saved for the time stamp: Millisecond or Microsecond
Attached element instance	The element can be assigned to a Trend visualization element. As a result, the time range of the trend element can be changed. The available visual elements are selected with the help of the Input Assistant.

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: `10`
Y	The Y-coordinate (in pixels) of the upper left corner of the element Example: `10`
Width	Specified in pixels Example: `150`
Height	Specified in pixels Example: `30`

Tip

You can change the values by dragging the box symbols to other positions in the editor.

Tick mark labels

Draw labels on two lines	: The time stamps are displayed on two lines. The date is displayed in the first line and the time is displayed in the second line. : The time stamp is displayed on one line. The date and time can also be displayed on one line depending on the formatting.
Omit irrelevant information in timestamps	: The display of the time stamps is shortened. For example, the date is displayed only for the first tick mark, and only the time for the following tick marks. When this setting is enabled, the settings in Internationalization (format strings) are ignored. : All information is displayed for all time stamps.
Internationalization (format strings)	Requirement: Only active when the parameter Omit irrelevant information in timestamps is deactivated. Format string, for example to adapt the display of the time values to local customs Note Basically, all `%t` format options are supported which are described in the "Placeholders with Format Definition" chapter.
Date	Format string for the date. The default setting is taken from the Windows control panel. Example: `dd.MM.yyyy`
Time	Format string for the time. The default setting is taken from the Windows control panel. Example: `HH:mm:ss:ms:Z`

Tip

You can programmatically switch the local time zone of the system time to universal time (UTC).

When the variable VisuElems.Visu_DateTime.DisplayUTC is set to TRUE, the system time is displayed as universal time (UTC). By default, the variable VisuElems.Visu_DateTime.DisplayUTC is set to FALSE so that the system time is displayed in the local time zone.

For the display of date and time values, you can extend the respective format string with the time zone code Z. For an output in local system time, the offset is then displayed in universal time (UTC). For example, dd:MM:yyyy HH:mm:ss:ms:Z outputs 01.08.2021 12:00:00:001:+02:00. When universal time (UTC) is displayed, the UTC code is also displayed. 01.08.2021 10:00:00:001:Z

Text properties

The properties get fixed values for the text properties and act on the texts configured in Texts → Text or Texts → Tooltip.

Horizontal alignment	Horizontal alignment of the text within the element
Vertical alignment	Vertical alignment of the text within the element
Font	Example: Default : The Font dialog opens. : List box with style fonts
Font color	Example: Black : The Color dialog opens. : List box with style colors
Transparency	Integer (value range from `0` to `255`) The transparent value determines the transparency of the respective color. `255`: The color is opaque. `0`: The color is completely transparent. Note If the color is a style color and already has a transparency value, then this property is write-protected.

Additional buttons

Jump to the largest possible time stamp	: An additional button is displayed for jumping to the last time stamp.
Jump to the smallest possible time stamp	: An additional button is displayed for jumping to the first time stamp.
Zoom out	: An additional button is displayed for setting the current min./max. range to the maximum range. The selected range is left.

Center

	The properties contain fixed values for the coordinates of the point of rotation. The rotation point is displayed in the editor as the symbol and is used as the center for rotation and scaling. Tip You can also change the values by dragging the symbol to another position in the editor.
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	Variable (numeric data type) for the X-position (in pixels) Example: `PLC_PRG.iPos_X` Container variable: `Container.Width` For more information, see the following: Optimally Adjusting the Position and Size Increasing this value at runtime moves the element to the right.
Y	Variable (numeric data type) for the Y-position (in pixels) Example: `PLC_PRG.iPos_Y` Container variable: `Container.Height` For more information, see the following: Optimally Adjusting the Position and Size Increasing this value at runtime moves the element downwards.
Rotation	Variable (numeric data type) for the angle of rotation (in degrees) Example: `PLC_PRG.iAngle1` The midpoint of the element rotates at the Center point. This rotation point is shown as the symbol. 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: `PLC_PRG.iAngle2` 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 symbol. Note If a static angle of rotation is specified in the Position → Angle 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.

State variables

The variables control the element behavior dynamically.

Invisible

Variable (BOOL) for toggling the visibility of the element

TRUE: The element is not visible at runtime.

Tip

The Invisible property is 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

Variable (integer value)
Example: Menu.tContent with VAR tContent : INT := 500; END_VAR
Integer literal
Example: 500

. Animatable properties

Absolute movement, Movement, X, Y
Absolute movement, Rotation
Absolute movement, Interior rotation
Absolute movement, Exterior rotation

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 (BOOL) for setting the element in the foreground

TRUE: At runtime, the visualization element is displayed in the foreground.

FALSE: At runtime, the visualization element is displayed in the layer where it was inserted in the visualization editor.

Example: bIsInForeground with VAR bIsInForeground : BOOL := FALSE; END_VAR

Permissions

Note

Available only when a user management is set up for visualization.
