textps documentation

textps is part of Antarctic Mapping Tools for Matlab (Greene et al., 2017). Click here for a complete list of functions in AMT.

The textps function works just like Matlab's text or textm functions, but places georeferenced text labels in Antarctic polar stereographic cartesian coordinates (true latitude 71°S). For example,

textps(lat,lon,'My text')

is equivalent to:

[x,y] = ll2ps(lat,lon);
plot(x,y,'My text')

Contents

Syntax

textps(lat,lon,'string')
textps(...,'PropertyName',PropertyValue,...)
textps(...,'km')
h = textps(...)

Description

textps(lat,lon,'string') adds the string in quotes to the location specified by the point (lat,lon) polar stereographic eastings and northings.

textps(...,'PropertyName',PropertyValue,...) formats the string with any name-value pairs of text properties.

textps(...,'km') plots in polar stereographic kilometers instead of the default meters.

h = textps(...) returns a column vector of handles to text objects, one handle per object.

Example

Place text labels in East and West Antarctica:

antbounds('gl')
textps(-80,-105,'West Antarctica')
textps(-75,90,'East Antarctica',...
  'fontangle','italic','color','red')
xlabel 'eastings (m)'
ylabel 'northings (m)'
