Visualization Element 'Cartesian XY Chart'dl-permalink__symbolPermalink

Symbol:

_cds_icon_xy_elem_2

Category: “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.

Constraint

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

in CODESYS Forge, 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”

_visu_icon_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

You can also change the values by dragging the box symbols (_visu_icon_position_element) 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”

_cds_icon_three_dots: Opens the “Font” dialog.

_cds_icon_arrow_down: List box with style fonts

Element property 'Control variables'

Table 665: “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
Table 666: “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 _visu_icon_center_point.png 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.

 _visu_img_prp_rotation

“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 _visu_icon_center_point.png 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.

 _visu_img_prp_inner_rotation

You can link the variables to a unit conversion.

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.

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

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”

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.
