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 1based, 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.
[Scale(code)] 
JR Viewer 
Sets the scaling code for the plot (linear, logarithmic, etc.). The low byte of code should be one of the following:
1 
Linear X, Linear Y 
2 
Linear X , Logarithmic Y 
3 
Logarithmic X, Linear Y 
4 
Logarithmic X, Logarithmic Y 
5 
Tripartite (loglog) scale 
6 
Linear X  Probability Y 
7 
Grain Size Distribution 
8 
Polar coordinates 
9 
Bar chart 
10 
Logarithmic X, Probability Y 
11 
Probability X, Linear Y 
12 
Probability X, Logarithmic Y 
13 
Probability X, Probability Y 
14 
Triangle Plot 
15 
N1.85 Hydraulic scale 
16 
Mercator projection 
The high byte of the scaling code contains scalingspecific information. Currently, this value is used only for tripartite grids, grain size distributions, and polar coordinates. For all other scale types, this value is reserved for future use and must be 0.
Tripartite grids
The high byte indicates what units to use for the grid. Supported values are:
Code 


5 

Hz, inches/sec, inches, and g's 
261 

Hz, feet/sec, feet, and g's 
517 

Hz, mm/sec, millimeters, and g's 
773 

Hz, cm/sec, centimeters, and g's 
1029 

Hz, meters/sec, meters, and g's 
1285 

Period (seconds), inches/sec, inches, and g's 
1541 

Period (seconds), feet/sec, feet, and g's 
1797 

Period (seconds), millimeters/sec, millimeters, and g's 
2053 

Period (seconds), centimeters/sec, centimeters, and g's 
2309 

Period (seconds), meters/sec, meters, and g's 
Grain size distributions
The high byte indicates what units the grain sizes are in. Supported values are:
Code 


7

263 

Inches 
Polar coordinates
The high byte indicates what units the angular dimensions are in. Supported values are:
Code
