geotickformat

Set or query geographic tick label format

Syntax

geotickformat fmt

geotickformat(fmt)

geotickformat(gx,fmt)

tickLabelFormat = geotickformat

tickLabelFormat = geotickformat(gx)

Description

geotickformat fmt sets the format of the latitude and longitude tick labels for the current geographic axes. When you use this syntax, you do not need to enclose the fmt argument in quotes. For example, the command geotickformat dd sets the tick label format to decimal degrees.

geotickformat(fmt) sets the tick label format for the current geographic axes. When you use this syntax, enclose the fmt input in single or double quotes, for example geotickformat('dd').

geotickformat(gx,fmt) sets the tick label format for the geographic axes specified by gx instead of the current geographic axes.

tickLabelFormat = geotickformat returns the tick label format for the current geographic axes.

tickLabelFormat = geotickformat(gx) returns the tick label format for the geographic axes specified by gx.

Examples

Set Geographic Tick Label Format

Set the tick label format for a geographic plot using geotickformat.

First, specify the coordinates of the three largest cities in Brazil.

lat = [-23.5500   -22.9083   -15.7939];
lon = [-46.6333   -43.1964   -47.8828];

Plot the coordinates and add text labels.

geoplot(lat,lon,'r.','MarkerSize',8)
geolimits([-25 -16], [-54 -38])
text(lat,lon,["Sao Paulo","Rio de Janeiro","Brasilia"])

Change the tick label format to decimal degrees using geotickformat. The cardinal directions of south and west are indicated by a minus sign.

geotickformat -dd

Input Arguments

Data Types: char | string

gx — Target geographic axes

GeographicAxes object

Target geographic axes, specified as a GeographicAxes object.^[1]

Tips

• The value returned from geotickformat is the value of the TickLabelFormat property of the geographic axes. You can override this format value on an individual axis by setting the TickLabelFormat property of the GeographicRuler object associated with the axis. In this case, the value returned by geotickformat does not match the format value of the axis or the actual display. Setting the TickLabelFormat of an individual axis is not recommended.
