Programmer's Reference > Sending data to DPlot from another application

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.

[SymbolFillBackground(state)]

JR Viewer

If state is non-zero, hollow symbols (not including Wingdings characters) will be filled with the plot background color, hiding any objects in the background including line segments and error bars for the same curve. If state=0, those symbols will be drawn with a transparent interior. The default plot background color is the window background color set with Control Panel. The plot background color may be changed with a BkColor command.

Example:

[SymbolFillBackground(0)]

[SymbolFillBackground(1)]
