Visualization Element 'Cartesian XY Chart'

Symbol:

Tag: Special Controls

The element displays the curve of array values graphically as a line or bar chart in the Cartesian coordinate system. The chart can display multiple curves at one time.

Notice

Constraint The element can be used with controller with V3.5 SP11 and later.

Note

In the CODESYS Store, you will find a sample project for using Cartesian XY Chart elements in visualizations.

Element properties

Element name

Example: Velocity chart

Type of element

Cartesian XY Chart

Cartesian XY Chart

XYChart: Opens the XY Chart Configuration dialog. This is where the chart is configured.

Element property 'Position'

The position defines the location and size of the element 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.

X

X coordinate of the upper left corner of the element

Specified in pixels.

Example: 10.

Y

Y coordinate of the upper left corner of the element

Specified in pixels.

Example: 10.

Width

Specified in pixels.

Example: 150

Height

Specified in pixels.

Example: 30

Note

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

Element property 'Element look'

The properties contain fixed values for defining the look of the element.

Border line width

Value (in pixels)

Example: 2

Note: The values 0 and 1 both result in a line weight of one pixel. If no line should be displayed, then the Border line style property must be set to the option Invisible.

Border line style

  • Solid

  • Dash

  • Dots

  • Dash Dot

  • Dash Dot Dot

  • Invisible

Frame line color

  • Style color from the list box. Example: Black

  • Fixed value that is selected in the color dialog. Example: 0; 0; 0

Element property 'Axis font'

Font

Example: Default

: Opens the Font dialog.

: List box with style fonts

Element property 'Control variables'

Zoom

Zooming the displayed curve is done by means of the mouse, or the pinch gesture on a multitouch device. It also applies to all axes.

At runtime when Enable is TRUE, you can draw a box with the mouse by holding down the left mouse button. When you release the mouse button, the display zooms in on the box and the curve is magnified. To zoom in and out on a multitouch device, move two fingers together or away from each other, respectively.

Zooming and panning can work together.

Enable

Variable (BOOL) that enables or disables zooming.

TRUE: Enables zooming

Example: PLC_PRG.xZoomEnable

Home

Variable (BOOL)

Rising edge: Reset the displayed curve to the initial state after the display has changed due to zooming.

Example: PLC_PRG.xZoomHome

Undo

Variable (BOOL)

Rising edge: Reset the displayed curve to the previous position after the display has changed due to zooming.

Example: PLC_PRG.xZoomUndo

Is zoomed

Variable (BOOL) that indicates whether or not the displayed curve was modified due to zooming.

TRUE: Curve setting was zoomed.

Example: PLC_PRG.xIsZoomed

Pan

Panning the displayed curve is done by means of the mouse or the pinch gesture on a multitouch device. It also applies to all axes.

At runtime if Enable is TRUE, then you can drag the displayed curve to another position by holding down the left mouse button. To pan the displayed curve on a multitouch device, drag it with one finger to another position.

Enable

Variable (BOOL) to enable or disable panning.

TRUE: Enables panning

Example: PLC_PRG.xPanEnable

Home

Variable (BOOL)

Rising edge: Reset the displayed curve to the initial position after the display has changed due to panning.

Example: PLC_PRG.xPanHome

Is panned

Variable (BOOL) whose state indicates whether or not the displayed curve was modified due to zooming.

TRUE: Curve setting was panned.

Example: PLC_PRG.xIsPanned

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: PLC_PRG.iPos_X.

Increasing this value in runtime mode moves the element to the right.

Y

Variable (numeric data type). Defines the Y position (in pixels).

Example: PLC_PRG.iPos_Y.

Increasing this value in runtime mode moves the element downwards.

Rotation

Variable (numeric data type). Defines 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.

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.

Interior rotation

Variable (numeric data type). Defines the angle of rotation (in degrees).

Example: PLC_PRG.iAngle2.

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 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.

Note

You can link the variables to a unit conversion.

Note

The X, Y, Rotation, and Interior rotation properties are supported by the "Client Animation" functionality.

Element property 'State variables'

The variables control the element behavior dynamically.

Invisible

Variable (BOOL). Toggles the visibility of the element.

TRUE: The element is not visible at runtime.

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

Deactivate inputs

Variable (BOOL). Toggles the operability of the element.

TRUE: User inputs do not have any effect in runtime more. The element is shown as deactivated.

Note

The Invisible property is supported by the "Client Animation" functionality.

See also

These properties are available only when you have selected the Preview: Support client animations and overlay of native elements option in the Visualization Manager.

Animation duration

Defines 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

Moves the visualization element to the foreground

Variable (BOOL)

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

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.

Element property 'Access rights'

Requirement: User management is set up for the visualization.

Access rights

Opens the Access rights dialog. There you can edit the access privileges for the element.

Status messages:

  • Not set. Full rights.: Access rights for all user groups : operable

  • Rights are set: Limited rights: Access is restricted for at least one group.
