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.
In data processing mode, modifies the primary record (pressure in a pressure-time history, acceleration in an acceleration-time history) so that the first integrated record (impulse or velocity, respectively) has an amplitude of value at time. Only shifts values of the primary record falling between the start and stop times. If start is a large negative number (< -1.E+19), the shift is applied to all amplitudes (the stop time is ignored). For more information see the description of the Baseline Shift menu command. As an alternative to this command, the Baseline Shift plugin (included with the licensed version) may be used to perform essentially the same task. The significant differences are that a) the plugin automatically determines the "time" value, b) "value" is always assumed to be 0, and c) it applies the shift to all points. To use the baseline shift plugin in a macro or DDE conversation, use [RunPlugin("Baseline Shift")]. This is a particularly handy tool when used in a ForFilesIn loop.
