linem
Project line object on map axes
Syntax
h = linem(lat,lon)
h = linem(lat,lon,linetype)
h = linem(lat,lon,PropertyName,PropertyValue,...)
h = linem(lat,lon,z)
Description
h = linem(lat,lon) displays
projected line objects on the current map axes. lat and lon are
the latitude and longitude coordinates, respectively, of the line
object to be projected. Note that this ordering is conceptually reversed
from the MATLAB® line function, because the vertical (y)
coordinate comes first. However, the ordering latitude, then longitude,
is standard geographic usage. lat and lon must
be the same size and in the AngleUnits of the map
axes. The object handle for the displayed line can be returned in h.
h = linem(lat,lon,linetype) where
linetype is a linespec that specifies the line style.
h = linem(lat,lon,PropertyName,PropertyValue,...)
allows the specification of any number of property name/property value pairs for any
properties recognized by the MATLAB
line function except for XData,
YData, and ZData.
h = linem(lat,lon,z) displays
a line object in three dimensions, where z is the
same size as lat and lon and
contains the desired altitude data. z is independent
of AngleUnits. If omitted, all points are assigned
a z-value of 0 by default.
The units of z are arbitrary, except when using the globe projection. In the case of globe,
z should have the same units as the radius of the earth or
semimajor axis specified in the 'geoid' (reference ellipsoid)
property of the map axes. This implies that when the reference ellipsoid is a unit
sphere, the units of z are earth radii.
linem is the mapping equivalent of the MATLAB line function.
It is a low-level graphics function for displaying line objects in
map projections. Ordinarily, it is not used directly. Use plotm or plot3m instead.
Examples
axesm sinusoid; framem linem([15; 0; -45; 15],[-100; 0; 100; 170],'r-')
