stem3m

Project stem plot on axesm-based map

Syntax

h = stem3m(lat,lon,z)
h = stem3m(lat,lon,z,LineSpec)
h = stem3m(lat,lon,z,PropertyName,PropertyValue,...)


Description

h = stem3m(lat,lon,z) displays a stem plot on the current axesm-based map. 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 axesm-based map. 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 axesm-based map are at most -π to +π and -π/2 to +π/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,LineSpec) specifies the line style, marker, and color.

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

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

Examples

Project a stem plot on a map.

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

More About

Line Style, Marker, and Color

Specify the line style, marker, and color as a character vector or string containing symbols. The symbols can appear in any order. You do not need to specify all three characteristics (line style, marker, and color). For example, specify a red dashed line using '--r'.

Line Style	Description	Resulting Line
"-"	Solid line
"--"	Dashed line
":"	Dotted line
"-."	Dash-dotted line

Marker	Description	Resulting Marker
"o"	Circle
"+"	Plus sign
"*"	Asterisk
"."	Point
"x"	Cross
"_"	Horizontal line
"|"	Vertical line
"square"	Square
"diamond"	Diamond
"^"	Upward-pointing triangle
"v"	Downward-pointing triangle
">"	Right-pointing triangle
"<"	Left-pointing triangle
"pentagram"	Pentagram
"hexagram"	Hexagram

Color Name	Short Name	RGB Triplet	Appearance
