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.

[LineWidth(curve,width)]

JR Viewer

Sets the width of the line segments used to draw curve number curve to width 1000'ths of an inch. If curve=-2, width is used for all curves. If curve=-1, width specifies the line width used for the coordinate axes. If curve=0, width is the line width used for grid lines and tick marks; if=-3, width is the line width used for intermediate grid lines (those drawn as a result of DenseGridLines).

For 3D data, curve=1 is used to set the line width for major contour lines, curve=2 is used for minor lines. The line width used for wireframe plots is set with curve=-4.
