SAC Command Reference Manual: SSS

DISTANCEAXIS

SUMMARY

Define the record section plot distance axis parameters.

SYNTAX

[D]ISTANCE[A]XIS FIXED v|SCALED v

INPUT

FIXED v:Force axis length to be $v$ cm long.
SCALED v:Allow the axis length to be scaled to the data. The axis length (in cm) will be the range of the axis (in km.) divided by v.

DEFAULTS VALUES

DISTANCEAXIS FIXED 35

DESCRIPTION

This command defines the properties of the distance axis for subsequent record section plots (see PLOTRECORDSECTION.) The length of the axis can be a fixed size or it can be scaled to the range of the axis variable (distance in this case.) The TIMEAXIS command controls the time axis properties.

EXAMPLES

If you entered the following command:

SAC> DISTANCEAXIS SCALED 2.0

and the minimum and maximum distances in the data set being plotted are 150 and 300 km respectively, the distance axis would be 75 cm long.

KNOWN BUGS

The y to x aspect ratio defined by this command and by the TIMEAXIS command is correct on plots to any device. The physical size requested is ignored when plotting to an interactive device (e.g. TERMINAL, XWINDOWS)

If the SGF device is requested, the physical size is stored in these files. The current SGF plot programs do not have the capability to make arbitrary sized plots (i.e. panelling). This panelling option is planned for a future release.
