Results
Reset Plots Now	Runtime command that resets the plotted data. Assign 'true' in the snippets to execute the command.	Runtime Command..	Boolean
XAML GazeVelocity Plot	Returns a live XAML control that can be used for direct binding to the Content property of the XAML ContentControl element, e.g. ContentControl with a generated staircase plot can be added to the status screen or to the XAML Layout element.	Normal..	UIElem..
Save GazeVelocity Plot Now	Assign a fully specified filename to save the generated plot to a file at runtime	Runtime Command..	String
Preview GazeVelocity Plot	Open a window with the gaze-velocity plot preview	Runtime Command..	Boolean
Gaze Processing
Tracking Device	Defines what tracking device provides positional samples for the element. The tracking devices include eye-trackers, the mouse and touch-screens. The 'Auto' option chooses the tracking device selected in the parent event. If there are no tracking elements enabled in the experiment, the system mouse is always used.	Design Time..	String
Sampling Rate	Defines the sampling rate of the tracking device  hardware in Hz. Keep the zero value for auto-detection.	Normal..	Double
Analysis Window Size	Defines the size of a moving analysis window in samples. The value also defines the data range in all generated plots	Design Time..	Int32
Exclusive Thresholds	Defines whether the exclusive velocity and saccade duration thresholds are used for the fixation detection by this element. The default value is false, which means that the same threshold values are shared with all eye-tracking analysis elements.	Design Time..	Boolean
X Velocity Threshold	Defines the saccade velocity threshold for the X-axes	Normal..	Double
Y Velocity Threshold	Defines the saccade velocity threshold for the Y-axes	Normal..	Double
Minimal Saccade Duration	Defines the minimal saccade duration threshold (in ms.) for the velocity-based detection algorithm. If a saccade candidate shorter than the threshold, it's discarded after completion. Note that, the element can still be triggered at the start and peak velocity of the discarded saccades, when the triggering mode is not 'On the saccade end'. If you do not want to apply the minimal duration threshold, set the zero value.	Normal..	Double
Maximal Saccade Duration	Defines the maximal duration threshold (in ms.) for the velocity-based detection algorithm. If a candidate saccade shorter than the threshold, it's discarded after completion. Note that, the element can still be triggered at the start and peak velocity of the discarded saccades, when the triggering mode is not 'On the saccade end'. If you do not want to apply the maximal duration threshold, set the zero value.	Normal..	Double
AOI
Element AOI	Selects a visual element, whose viewport defines an on-screen AOI for the eye-tracking analysis.	Normal..	Int32
Custom AOIs	Selects a visual element, whose viewport defines an on-screen AOI for the eye-tracking analysis.	Normal..	IColle..
Detection Results
Current X Velocity	Returns the current gaze velocity along the X-axes. The value is read-only.	Status..	Double
Current Y Velocity		Status..	Double
General Plot Settings
Rendering Size	The rendering size also defines the image resolution, when the plot is saved into an image file or video.	Normal..	clSize
Show Axis	Defines whether the axis are visible on the plot	Normal..	Boolean
Show Gridlines	Defines whether the major tick gridlines are shown on the plot.	Normal..	Boolean
Add Screen Clone	Defines whether a clone of the presentation screen is shown at the background of the plot.	Design Time..	enScre..
Rendering Quality	Defines the quality and speed the plot rendering	Normal..	Int32
Plot Theme	Defines a visual theme for the plot	Normal..	Int32
Control
Is Enabled	If set to false the element is completely omitted when the experiment is run	Design Time..	Boolean
Title	Title of the element	Design Time..	String
