| Reset Plots Now | Runtime command that resets the plotted data. Assign 'true' in the snippets to execute the 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. | | UIElem.. | |
| Save GazeVelocity Plot Now | Assign a fully specified filename to save the generated plot to a file at runtime | | String | |
| Preview GazeVelocity Plot | Open a window with the gaze-velocity plot preview | | 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. | | String | |
| Sampling Rate | Defines the sampling rate of the tracking device hardware in Hz. Keep the zero value for auto-detection. | | 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 | | 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. | | Boolean | |
| X Velocity Threshold | Defines the saccade velocity threshold for the X-axes | | Double | |
| Y Velocity Threshold | Defines the saccade velocity threshold for the Y-axes | | 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. | | 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. | | Double | |
| AOI |
| Element AOI | Selects a visual element, whose viewport defines an on-screen AOI for the eye-tracking analysis. | | Int32 | |
| Custom AOIs | Selects a visual element, whose viewport defines an on-screen AOI for the eye-tracking analysis. | | IColle.. | |

| Current X Velocity | Returns the current gaze velocity along the X-axes. The value is read-only. | | Double | |
| Current Y Velocity | | | 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. | | clSize | |
| Show Axis | Defines whether the axis are visible on the plot | | Boolean | |
| Show Gridlines | Defines whether the major tick gridlines are shown on the plot. | | Boolean | |
| Add Screen Clone | Defines whether a clone of the presentation screen is shown at the background of the plot. | | enScre.. | |
| Rendering Quality | Defines the quality and speed the plot rendering | | Int32 | |
| Plot Theme | Defines a visual theme for the plot | | Int32 | |
| Control |
| Is Enabled | If set to false the element is completely omitted when the experiment is run | | Boolean | |
| Title | Title of the element | | String | |
