stem3m

Project a stem plot map on the current map axes

Syntax

h = stem3m(lat,lon,z) displays a stem plot on the current map axes. Stems are located at the points (lat,lon) and extend from an altitude of 0 to the values of z. The coordinate inputs should be in the same AngleUnits as the map axes. It is important to note that the selection of z-values will greatly affect the 3-D look of the plot. Regardless of AngleUnits, the x and y limits of the map axes are at most - to + and -/2 to +/2, respectively. This means that for most purposes, appropriate z values would be on the order of 1 to 3, not 10 to 30. The axes DataAspectRatio property can be used to adjust the appearance of the graphic. The handles of the displayed stem lines can be returned in h.

h = stem3m(lat,lon,z,LineType) allows the style of the stem plot's lines to be specified with any string LineType recognized by the MATLAB line function.

h = stem3m(lat,lon,z,PropertyName,PropertyValue,...) allows any property/value pair recognized by the MATLAB line function to be specified for the stems.

Description

A stem plot displays data as lines extending normal to the xy-plane, in this case, on a map.

Examples

• load coast
  axesm sinusoid; view(3)
  h = framem; set(h,'zdata',zeros(size(lat)))
  plotm(lat,long)
  ptlat = [0 30 30 -50 -78]';
  ptlon = [0 30 -70 65 -35]';
  ptz = [1 1.5 2 .5 1]';
  stem3m(ptlat,ptlon,ptz,'r-')
