EditRemoveSpikes macro command

Print this Topic Previous pageReturn to chapter overviewNext page

Macro commands may be used either in macros or by sending the commands to DPlot via dynamic data exchange (DDE). Some commands are valid only in macros (noted by Macros Only). Commands sent to DPlot via DDE must be enclosed by square brackets [     ]. Macro commands should not include the brackets.

Command parameters shown in the descriptions below are placeholders for the actual values. Command parameters are either numeric values, equations that evaluate to numbers, or character strings. Character string parameters are always bound by double quotation marks. Equations must be preceded by an equals sign (=).

The pipe symbol (|) in the command syntax indicates that a parameter is optional, and should not be included in your macro unless otherwise noted.

All indices into arrays are 1-based, e.g. Curve1=1 refers to the first curve in a plot.

A 0x prefix for numbers in the descriptions below indicates hexadecimal notation; e.g. 0x0010 = 16.

JR/Viewer indicates that the command is supported by DPlot Jr or DPlot Viewer.
JR/Viewer indicates that the command is NOT supported by DPlot Jr or DPlot Viewer.



JR   Viewer

Removes single samples with high amplitudes which bear no relation to the true record from the curve or curves specified with the SelectCurve command. This command performs the same operation as the Remove Random Spikes command on the Edit menu.

The conditions defining a spike at point n are:

The condition which defines the sizes of spikes to be removed is:

where Range is the current range in amplitudes for the record. If any sample in a record meets both of the conditions described above, it is considered a spike and replaced with the average of the adjacent values.

All parameters are optional. If SpikeLow, SpikeHigh, or SpikeRatio are omitted, default values of 0.75, 1.25, and/or 0.1, respectively, will be used. All points in a curve will be operated on unless both X1 and X2 (lower and upper limits) are specified.
