Greetings,

I am trying to create a map for a publication and I would like to (easily) change the FontSize of my map axes and still have the axes printed inside the figure.

I am using the following code:

latLim = [-53.7 -52];
lonLim = [-41 -39.2];
figure
h = worldmap(latLim, lonLim);
setm(gca, 'FontSize', 20);

This code yields to this figure:

As you might notice, the longitudes are cropped.

PS: I want to keep the following:

get(gcf, 'position')
ans =
   560   528   560   420

How can I make sure the map will be plotted in a correct manner inside this figure?

Try to reduce the axes size

latLim = [-53.7 -52];
lonLim = [-41 -39.2];
figure
h = worldmap(latLim, lonLim);
setm(gca, 'FontSize', 14);
h.Position(4) = h.Position(4)-0.1;

Overall, I find Matlab graphics function to be convenient, however, I never used worldmap() before. I agree that the way worldmap is created, is a real mess. I don't think there is an easy way to rotate the labels. Following shows a workaround, but making any adjustment to the position of labels is quite difficult.

latLim = [-53.7 -52];
lonLim = [-41 -39.2];
figure
h = worldmap(latLim, lonLim);
setm(gca, 'FontSize', 14);
h.Position(4) = h.Position(4)-0.1;
lbls = findobj(h, 'Tag', 'PLabel');
[lbls.HorizontalAlignment] = deal('center');
[lbls.Rotation] = deal(-90);
for i=1:numel(lbls)
    lbls(i).Position = lbls(i).Position - 15000;
end
