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.

Project Stem Plot on Map

Open Live Script

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-')

Figure contains an axes object. The axes object contains 4 objects of type patch, line.

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
`"red"`	`"r"`	`[1 0 0]`
`"green"`	`"g"`	`[0 1 0]`
`"blue"`	`"b"`	`[0 0 1]`
`"cyan"`	`"c"`	`[0 1 1]`
`"magenta"`	`"m"`	`[1 0 1]`
`"yellow"`	`"y"`	`[1 1 0]`
`"black"`	`"k"`	`[0 0 0]`
`"white"`	`"w"`	`[1 1 1]`
