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.
[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 (log-log) 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 scaling-specific 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 |
|
Millimeters |
263 |
|
Inches |
Polar coordinates
The high byte indicates what units the angular dimensions are in. Supported values are:
Code |
|
|
8 |
|
Radians |
264 |
|
Degrees |
