m_track(lon,lat,varargin);
M_TRACK Draw a trackline on a map
M_TRACK draws navigation tracklines on a map. The trackline
itself is optionally annontated with tick marks, time labels, and
date labels.
M_TRACK (lon,lat) draws just a plain line. lon&lat are in decimal
degrees, +N, -S, +E, -W.
M_TRACK (lon,lat,navtimes) draws a line, with tick marks every
hour, time labels every four hours, and date labels every twelve
hours. navtimes is in MatLab "serial date numbers," representing the
number of days since January 1, 0000. By convention, ticks and
time labels are drawn on the starboard side, dates on the port.
M_TRACK (lon,lat,navtime, 'string', property/value pairs) can be
used to change tick marks, time and date label properties. Allowable
combinations are:
'ticks' tickmark interval in minutes, default=60
'times' time label interval in minutes, default=240 (4hrs)
'dates' date label interval in minutes, default=720 (12hrs)
'timef[ormat]' format of time string, see datestr(), default=15
'datef[ormat]' format of date string, see datestr(), default=2
'color' color of track/labels, default is black
'linew[idth]' width of trackline, default is current
'lines[tyle]' style of line, default is solid line
'fonts[ize]' size of font, default is current
'fontn[ame]' name of font, default is current
'clip' 'on' or 'off' (clipping to map)
'orien[t]' label orientation, 'true' or 'upright', default='true'
time labels need to be whole multiples of tick intervals. date
labels need to be whole multiples of time labels. using '0' for
any value will tick/label all points. using a negative number
will suppress tick/label.
