The Data analysis / Display control panel is located in the right panel of the Display window (Figure D).
The possible type of display and actions related to XY relationships depend on the type of signals connected in input.
Input status  Display mode  Available control panel(s) 
X continuous 


Y connected  2D, 3D  Curve fitting, 3D display settings 
Y connected  2D   
Y not connected  2D, 3D  3D display settings 
X discrete 


Y connected, ≠X  2D  Discrete signals points matching, Curve fitting 
Y connected, =X  2D  Discrete signals points matching, Curve fitting

3D display settings
The 3D display settings panel is available for XY plots of continuous signals with Trigger connected in input. The 3D display is associated to the 3D button located below XY display.
Angle and Depth parameters can be changed in the control panel or directly in the XY display by holding down the left button of the mouse and then moving the pointer to the desired position. Values of Angle and Depth in the control panel are automatically adjusted.
Item  Description  Default  Range  Units 
Angle  3D display angle  45  [180;180]  Deg 
Depth  3D display depth  Automatically adjusted in order to have the first cycle fitted in the display.  [1;300]  Pixel 
Show before trigger  Duration before trigger during which signal is displayed.  100  [0;360000]  ms 
Show after trigger  Duration after trigger during which signal is displayed.  100  [0;360000]  Ms 
Discrete signal points match
The Discrete signal points match panel (described in the table below) is available when the signal connected on X input is discrete. It allows to defined the reference point for XY pairs and the association method.
For discrete input signals settings adapt whether X and Y inputs are identical or not.

Matching algorithms
 X master Y master Y = X + n samples Y = X + time 



Number of samples  Userdefined number of samples.  1  [1;1000]   
Time  Userdefined duration.  1000  [0;no upper limit]  ms 
Matching window  Userdefined time window for XY matching (unselected by default).  100  [0;no upper limit]  ms 
The selection of matching algorithm and associated parameters depends on characteristics of the X and Y inputs .
Mode  Description  Associated parameter 
Same signal connected to X and Y inputs  
Y = X + n samples  Each value is associated to another one, distant by a userdefined number of samples.  Number of samples 
Y = X + time  Each value is associated to another one, distant by a userdefined duration.  Time (ms) 
Different signals connected to X and Y inputs  
X master  Each value on X signal is associated to the first encountered value on Y signal after the X point.  Matching window (ms) 
Y master  Each value on Y signal is associated to the first encountered value on X signal after the Y point.  Matching window (ms) 
Curve fitting
The user can select and apply a fitting curve to the XY relationship of each zone. The regression equation and correlation coefficient is displayed in the Curve fitting control panel. Approximation of XY plot is available with Linear, Exponential, Quadratic or Logarithmic formulas.
Curve fitting is available for both discrete and continuous signals.
For continuous signals, conditions apply:
 X, Y and Trigger inputs must be connected,
 2D mode must be selected,
 regression curve is computed with X and Y values at the time of the trigger.
Parameters of the fitting curve control panel:
Method  Value 
Linear  Y = a*X + b 
Quadratic  Y = a*X2 + b*X + c 
Exponential  Y = a*exp(b*X) + c 
Logarithmic  Y = a*ln(b*X) + c
