Charts

Chart How to plot Description of the chart

Raw data per trial
(MovAlyzeR & ScriptAlyzeR)

 Right click on the trial > chart data > chart raw data

This will chart the raw position data as X versus Y (that may extend for the first 2-3 charts)

Additional charts include X,Y and Z as a function of time (sampling coordinates).

Raw data per trial
(GripAlyzeR)		 Right click on the trial > chart data > chart raw data

The Raw Data charts display the following forces for each trial:

~LowerGrip (N) and UpperGrip (N) as a function of sample number
~ Load (N) as a function of sample number.

All forces are calibrated in Newtons

Raw data per subject Right-click on the subject > plot all raw data

Shows all the raw data for a particular subject in an experiment.

Note: In the case of very data intensive recordings, the time taken to display this chart is comparatively increased.

Raw data in real-time per trial Right click on the trial > chart data > chart real-time data This shows the data as it was recorded in real time by the subject. This option is useful in determining glitches during recording.

Raw data in 3D per trial
(MovAlyzeR & ScriptAlyzeR)

 Right click on the trial > chart data > chart raw data (3D)

This will chart the raw position data as Y versus X (that may extend for the first 2-3 charts) with Z as a third dimension

Additional charts include X,Y and Z as a function of time (sampling coordinates).

Processed data per trial
(MovAlyzeR & ScriptAlyzeR)

Double-click a particular trial

<OR>

Right click on the trial > chart data > chart processed data

Charts Time Function Data in X versus Y.

Additional charts include positions, Z-coordinate, velocities, accelerations, jerks in X, Y, or absolutely. All curves are calibrated in units of cm and s.

Processed data per trial
(GripAlyzeR)

Double-click a particular trial

<OR>

Right click on the trial > chart data > chart processed data

o Lower versus Upper Grip Forces to estimate their proportionality.
o LowerGrip versus Load Forces to estimate their proportionality.
o UpperGrip versus Load Forces to estimate their proportionality.
o LowerGrip (N) as a function of time.
o UpperGrip (N) as a function of time.
o UpperLoad (N) as a function of time (showing the proper segmentation)
o vLowerGrip (N/s) = Change of Lower Gripper Force in Newton/s
o vUpperGrip (N/s) = Change of Upper Gripper Force in Newton/s
o vLoad (N/s) = Change of Load Force in Newton/s
o aLowerGrip (N/s**2) = Acceleration of the Lower Gripper Force in Newton/s2
o aUpperGrip (N/s**2) = Acceleration of the Upper Gripper Force in Newton/s2
o aLoad (N/s**2) = Acceleration of the Load Force in Newton/s2
o V_Spectrum = Amplitude Spectrum of Lower and UpperGrip forces (i.e., absolute spectrum multiplied by 2*pi*Frequency in Newton/s)
o V_Spectrum_Filtered = Lowpass Filtered Amplitude Spectrum

Processed data in real-time per trial

Right click on the trial > chart data > chart processed data real-time

This shows the data as it was recorded in real time by the subject. This option is useful in determining glitches during recording.

Processed data per trial
(MovAlyzeR & ScriptAlyzeR)

Right click on the trial > chart data > chart processed data (3D)

Charts Time Function Data in Y versus X with Z as the third dimension.

Additional charts include positions, Z-coordinate, velocities, accelerations, jerks in X, Y, or absolutely. All curves are calibrated in units of cm and s.

Examples

RAW DATA CHART PER TRIAL

CHART ALL RAW DATA PER SUBJECT

PROCESSED DATA CHART

o Stroke segmentations are marked by o.

o The submovement points are denoted by a X.

3D DATA CHART

Submovement Analysis (MovAlyzeR ONLY)

Example of a movement segmented by (o) and a submovement segmentation (x) between primary and secondary submovements if submovement analysis is enabled in the Experiment Settings.

 

Graphical Button Descriptions

From left to right (some buttons apply only to certain charts):

- New Chart - Opens another chart of your choosing (raw, processed, real-time, 3D)

- View Numerical Data - Display the data used to generate the chart

- Extracted Data - Display the extracted data for that trial

- Consistency Errors - Display the consistency results for that trial

- Export - Export the chart to an image, clipboard, or printer

- Print - prints the chart

- Line Thickness - Allows you to choose the line thickness for the chart

- Proportional Scaling - Choose between proportional and optimal scaling

- Monochrome - Choose between color and monochrome display

- Invert (3D only) - Inverts the Y and Z axes

- X/Y Values - Toggles the X/Y values at each segmentation point

- Segmentation Points - Toggles the display of segmentation points

Spectral Analysis

o The TF charts include the frequency spectra before and after filtering to allow inspection of whether signal frequencies have been filtered. The horizontal axis is calibrated in Hz.

 

o The vertical axis is calibrated in terms of velocity. This yields a balanced spectrum between low and high frequency components.

o The height of this spectrum at a certain frequency corresponds to the average, absolute velocity observed for that frequency.
