EditDecimate 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

Decimates data values in the curve or curves selected with the SelectCurve command. Method = 0 to average every value points, = 1 to discard all but every value'th point, or = 2 to use the Welch depopulation scheme with fidelity = value. Replace = 1 to replace existing data points, = 0 to preserve the original data and produce a new curve. Operates on data points between X = start and X = stop. Start and stop are each optional; if start is omitted then the minimum X value for the curve is used; if stop is omitted then the maximum X value for the curve is used. If both are omitted then the entire curve will be operated on.
