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.

[PolarPlotStyle(flags)]

JR Viewer

Changes the appearance of polar plots. Flags is a combination of:

0x0001

0 degrees is at the top of the plot, rather than the default right.

0x0002

Angles are measured clockwise rather than the default counterclockwise.

0x0004

Forces a circular plot.

0x0008

Radial axis labels are vertical.

0x0010

Radial labels are centered on the radius.

0x0020

0 degrees is labelled.

0x0040

Angles are displayed as 0 to +180 degrees rather than the default 0 to 360.

0x0080

Transform points with negative radii to angle+180 degrees, radius=abs(radius). Note that unlike other options this operates on the actual data values and is therefore not reversible. The value added to the angle (X) coordinates is either 180 for angles in degrees or PI for angles in radians.

0x0400

Angles are in degrees rather than the default radians.

0x7000

Bits determining at which radial line the axial grid lines start.
0x0000 Center of plot
0x1000 1st radial line
0x2000 2nd radial line
0x3000 3rd radial line
0x4000 4th radial line
0x5000 5th radial line
0x6000 6th radial line
0x7000 7th radial line

Combine flags options by adding them.
