Scaling Code

The low byte of the scaling code indicates what type of scaling the plot should use. Currently supported values are:

1	Linear X, Linear Y

2	Linear X , Logarithmic Y

3	Logarithmic X, Linear Y

4	Logarithmic X, Logarithmic Y

5	Tripartite grid

6	Linear X - Probability Y

7	Grain Size Distribution

8	Polar coordinates

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. Currently supported values are:

Units Code	Scaling Code
0	5	Hz, inches/sec, inches, and g's
1	261	Hz, feet/sec, feet, and g's
2	517	Hz, mm/sec, millimeters, and g's
3	773	Hz, cm/sec, centimeters, and g's
4	1029	Hz, meters/sec, meters, and g's
5	1285	Period (seconds), inches/sec, inches, and g's
6	1541	Period (seconds), feet/sec, feet, and g's
7	1797	Period (seconds), millimeters/sec, millimeters, and g's
8	2053	Period (seconds), centimeters/sec, centimeters, and g's
9	2309	Period (seconds), meters/sec, meters, and g's
127	32517	User-defined units.

Grain size distributions

The high byte indicates what units the grain sizes are in. Currently supported values are:

Units Code	Scaling Code
0	7	Millimeters
1	263	Inches
127	32519	User-defined units

Polar coordinates

The high byte indicates what units the angular dimensions are in. Currently supported values are:

Units Code	Scaling Code
0	8	Radians
1	264	Degrees

A DPlot file saved with "user-defined" units should also contain the miscellaneous identifier "units".
