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.

[Color(index,r,g,b)]

JR Viewer

Sets the color for the index'th curve of an XY plot to the color with red, green, and blue components r,g,b, where r,g, and b range from 0 to 255. If index = -1, then r,g,b are used for ALL curves.

[Color(3,255,0,255)]

sets the color for the third curve to magenta, and

[Color(-1,0,0,0)]

sets the color for all curves to black.

If index=0, r,g,b represent the color components for grid lines. For XY and 1D plots, the default grid line color is a light gray (192,192,192). For 3D plots the default grid line color is black (0,0,0).

For 3D/4D data only, if index=-2, r,g,b represent the color components for the border lines (lines drawn when "Borders" on the Contour Options dialog is checked.)
