stem3m

Project stem plot on map axes

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 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 -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.

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
