Description


The Scale Data feature offers an automated environment for data scaling, allowing such operations as normalization, raising to an arbitrary power, Scaling by a constant and many others.

 

 

Navigation


This feature can be accessed by right mouse clicking on an active 3D chart view and selecting "Scale Data" from the list menu.

Inputs / Description

Defaults

Scaling Operation

Normalize max value to

Dataset max value set to user input value.

1

Raise to the power of

Dataset raised to the power of the user input value.

1

Scale by

Dataset scaled by the user input value.

1

Scale to min/max value

Dataset re-scaled between min and max value input by the user.

0, 1

Log (base 10), Set floor

Takes log10 of the dataset. Displays user input number of decades below the max. The number of decades MUST be negative.

-6

Show floor

Fill in unplotted pixels at the floor value of the log10 scaling.  If there are no unplotted pixels, then this command has no effect.

Unchecked

Normalized db (decibels)

Normalize data to unity (1) then take 10*log10 of the data.

Not selected

Anti-logarithm (base 10)

Exponentiate dataset.

Not selected

Square root

Takes the square root of the data.

Not selected

Axis Label and Min/Max Events

Use default values

Use the default min and max values for the data axis.

Selected

Set min, max

Use the user input min and max for the data axis.

0, 1

Label

Label name for the data axis.

Irradiance or Intensity

Specify Which Dataset to Use

Use current dataset for scaling

 Use the current data set for scaling.

Selected

Save dataset snapshot before scaling

N/A - this option only applies to Legacy chart scaling (which shares the same dialog) and is not selectable within a LightningChart.

Not selected

Restore original dataset before scaling

Restore the original dataset before performing the scaling operation.  NOTE: LightningChart charts retain the original data set, making it trivial to restore data in any open LightningChart

Not selected

Not selected

 

OK

Accept settings and close dialog box.

 

Cancel

Discard settings and close dialog box.

 

Apply

Apply settings and keep dialog box open.

Application Notes


Recovering original data

In a LightningChart chart the original data is saved in it's own grid, and so can be recovered very simply even after the dialog is closed using the restore original data option. This is a key difference between LightningChart and Legacy Charts (which do not offer non-trivial data restoration).
