Visualization Element: Cartesian XY Chart

Symbol:

Category: Special Controls

The element graphically displays the curve of array values 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.

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: Velocity chart

Tip

Assign individual names for elements so that they are found faster in the element list.

Type of element

Cartesian XY Chart

XYChart: Opens the XY Chart Configuration dialog.

There you can configure the chart.

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.

Element appearance

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

Font axes

Font	Example: Default : Opens the Font dialog. : List box with style fonts

Control variables

Table 14. 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.
Activate	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 15. 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.
Activate	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`

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.

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

Deactivate inputs

Variable (BOOL) for toggling the operability of the element

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

Tip

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

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

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.

Access Rights button

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.
