contour3m

Project a contour plot of map data in 3-D space

Syntax

• c = contour3m(lat,lon,map)
  c = contour3m(lat,lon,map,LineType)
  c = contour3m(lat,lon,map,PropertyName,PropertyValue,...)
  
  c = contour3m(lat,lon,map,n,...)
  c = contour3m(lat,lon,map,v,...)
  [c,h] = contour3m(lat,lon,map,...)
  

Description

contour3m(lat,lon,map) produces a 3D contour plot of map data projected onto the current map axes. The input latitude and longitude vectors can be the size of map (as in a general matrix map), or can specify the corresponding row and column dimensions for the map

contour3m(map,maplegend) produces a contour plot of map data in a regular matrix map.

contour3m(lat,lon,map,LineSpec) uses any valid LineSpec string to draw the contour lines.

contour3m(lat,lon,map,PropertyName,PropertyValue,...) uses the line properties specified to draw the contours.

contour3m(lat,lon,map,n,...) draws n contour levels, where n is a scalar.

contour3m(lat,lon,map,v,...) draws contours at the levels specified by the input vector v.

contour3m(map,maplegend,...) takes any of the optional arguments described above.

c = contour3m(...) returns a standard contour matrix, with the first row representing longitude data and the second row represents latitude data.

[c,h] = contour3m(...) returns the contour matrix and the handles to the contour lines drawn.

contour3m, without any inputs, will activate a GUI to project contour lines onto the current map axes.

Examples

• load topo
  axesm robinson; framem; view(3)
  contour3m(topo,topolegend)
  set(gca,'DataAspectRatio',[1 1 3000])
