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

Restriction 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 XY chart elements in visualizations.

Element property 'Access rights'

Element properties

Element name	Example: Velocity chart
Type of element	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

Dashes

Dots

Dash Dot

Dash Dot Dot

Hollow

Frame line color

Style color from the drop-down list. 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. : Drop-down list 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.

Client Animation

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.

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.

Client Animation

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

You can animate a movement, a rotation, and the visibility of a visualization element.

Animation time

Time that the element executes an animation (in milliseconds)

Example: 500

Move to the foreground

Property value (BOOL)

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

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