MATLAB: How to change size of axis labels in MappingToolbox, as well as ColorBar axis size

axislabelMapping Toolboxplotscattersetm

I have been struggling to change the size of the Latitude and Longitude values on the axis of my mapping plots in the Mapping Toolbox.

I would want to increase the size of those numbers as well as the size of the axis values on the ColorBar. I tried to use axesm(), but I keep getting an error about a Projection Map.

latlim = [25 50]; lonlim = [-105 -67];
axe = usamap(latlim, lonlim);
set(axe, 'Visible', 'off');
sheds = shaperead('usastatehi','UseGeoCoords', true, 'BoundingBox', [lonlim', latlim']);
geoshow(axe, sheds, 'FaceColor', [1 1 1])
%axesm('FontSize', 15) % This doesn't work. 
 
scatterm(lat, long, 15, ftratio, 'filled')
 
 
caxis([0 3]);

Use setm() to set properties of map axes.

setm(axe, 'FontSize', 15)

MATLAB: How to set usamap projection to mercator

Hello Leon,

Once you use geoshow to place shapes onto the map, you cannot change the map projection. You could delete all the children, change the projection, and then reuse geoshow. But an easier way is to just set the map projection at the outset:

ax = usamap([10 90], [-180 -50] );
states = geoshape(shaperead('usastatehi', 'UseGeoCoords', true));
oceanColor = [.5 .7 .9];
setm(ax, 'FFaceColor', oceanColor)
setm(ax,'MapProjection','mercator')  % ADDED LINE
geoshow(states)
gridm off;

You can see an example here.

figure
ax = usamap('all');
set(ax, 'Visible', 'off')
states = shaperead('usastatelo', 'UseGeoCoords', true);
names = {states.Name};
indexHawaii = strcmp('Hawaii',names);
indexAlaska = strcmp('Alaska',names);
indexConus = 1:numel(states);
indexConus(indexHawaii|indexAlaska) = []; 
stateColor = [0.5 1 0.5];

Display the three regions.

geoshow(ax(1), states(indexConus),  'FaceColor', stateColor)
geoshow(ax(2), states(indexAlaska), 'FaceColor', stateColor)
geoshow(ax(3), states(indexHawaii), 'FaceColor', stateColor)

Hide the frame.

for k = 1:3
    setm(ax(k), 'Frame', 'off', 'Grid', 'off',...
      'ParallelLabel', 'off', 'MeridianLabel', 'off')
end

Add labels to each state.

lat = [states(indexConus).LabelLat];
lon = [states(indexConus).LabelLon];
textm(lat, lon, {states(indexConus).Name},'HorizontalAlignment', 'center','Parent',ax(1));
latA = [states(indexAlaska).LabelLat];
lonA = [states(indexAlaska).LabelLon];
textm(latA, lonA, {states(indexAlaska).Name},'HorizontalAlignment', 'center','Parent',ax(2));
latH = [states(indexHawaii).LabelLat];
lonH = [states(indexHawaii).LabelLon];
textm(latH, lonH, {states(indexHawaii).Name},'HorizontalAlignment', 'center','Parent',ax(3));
