plot3m

Project 3-D lines and points on map axes

Syntax

h = plot3m(lat,lon,z)
h = plot3m(lat,lon,linespec)
h = plot3m(lat,lon,PropertyName,PropertyValue,...)

Description

h = plot3m(lat,lon,z) 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. z is the altitude data associated with each point in lat and lon. The object handle for the displayed line can be returned in h.

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.

h = plot3m(lat,lon,linespec) where linespec specificaties the line style.

h = plot3m(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.

Examples

axesm sinusoid; framem; view(3)
[lats,longs] = interpm([45 -45 -45 45 45 -45]',...
                       [-100 -100 100 100 -100 -100]',1);
z = (1:671)'/100;
plot3m(lats,longs,z,'m')

Tips

plot3m is the mapping equivalent of the MATLAB plot3 function.
