# plot3m

Project 3-D lines and points on map axes

## Syntax

`h = plot3m(lat,lon,z)h = plot3m(lat,lon,linetype)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,linetype)` allows the specification of the line style, where `linetype` is any string recognized by the MATLAB `line` function.

`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.
