VectorPlotOptions 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

Sets several options for the appearance of vector plots.

flags is a combination of:

0x0001Angles are specified in degrees rather than the default radians.
0x0002Angles are measured clockwise. Default is counterclockwise.
0x00040 degrees is in the positive Y direction. Default is in the positive X direction.
0x0008Vector centered on point. Default is with vector tail at the point.
0x0010Discrete colors. Default is to blend colors between various magnitudes.
0x0020Draw color key
0x0040Specify magnitudes associated with each color. The default is to use equal intervals between the low and high values of the magnitude source curve.

Combine flags options by adding them.

arrowheight is the height of the vector arrowheads, in thousandths of inches. Default value is 150.

linewidth is the width of the vector lines, in thousandths of inches. A value of 0 results in 1 unit (1 pixel, 1 printer dot, etc.) lines.
