MATLAB: Axis fontsize and text fontsize not matching

fontsize font size text axisMATLAB

I am using the code below that shows the same text as axis xlabel and as a text object. These two labels appear in different sizes despite both being defined at the same size (10 points). I tried on both Windows and Mac. Also in both 2017b and 2018a versions. same problem appears.

lbl = 'These two labels should have the same fontsize 10 yet appear with different sizes' ;
figure(1);clf
set(gcf,'position',[100 100 700 700]) 
plot([0 1],[0 1],'r')
xlabel(lbl)
text(0.5,-0.1, lbl, 'units','normalized', ...
     'HorizontalAlignment','center','fontsize',10)
set(gca,'fontsize',10)

Dear Royk,

try this:

lbl = 'These two labels should now have the same fontsize 10' ; 
figure(1);clf 
set(gcf,'position',[100 100 700 700]) 
plot([0 1],[0 1],'r') 
A = xlabel(lbl);
A.FontSize = 10;
text(0.5,-0.1,lbl,'units','normalized','HorizontalAlignment','center','fontsize',10);

best, Sandro

MATLAB: Changing only axis fontsize

As you are excluding legend and colorbar from your axes, we deduce that you are using R2014a or earlier; in R2014b and later, legend and colorbar are not axes.

With R2014a or earlier, there is only one font size property for axes.

In order to change the font size of only the labels, you need to use a technique similar to what is used in https://www.mathworks.com/matlabcentral/fileexchange/3486-xticklabel-rotate where the automatic labels are found and are replaced by text objects that have the desired properties.

If you were using R2014b or later, you could avoid all of that by setting the XAxis.Fontsize or YAxis.FontSize properties of the axes.

MATLAB: More on the menu fontsize

You misinterpretted by intent. It IS possible to do this, just not with the stock menu() function. You'll have to write your own menu() function (basically a modal figure with a few uicontrols that returns a number. Since you'll be constructing the uicontrols yourself you can give them a nice large fontsize. It should be pretty straightfoward.

Here is something I threw together that should do what you want. It's a bit sloppy on the positioning but could be easily modified to be made pretty:

function selection = mymenu(question,varargin)
%Simple my menu
%



%Usage:
%   -selection = mymenu('Choose one please:','monday','tuesday','wednesday')
%
%Inputs:
%   -question: string with question
%   -options: n strings of options
%
%Outputs:
%   -selection: index of selected button
%
      %Error checking:
      assert(nargin >=2 ,'At least two inputs expected');
      assert(ischar(question),'question should be a string');
      assert(all(cellfun(@ischar,varargin)), 'options should be strings')
      %Build figure:
      n = length(varargin); %number of options
      hF = figure('windowstyle','modal','units','pix','position',[300 300 200 (n+1)*80]);
      uicontrol('style','text','position',[10 (n+1)*70,100,20],'string',question);
      for ii = n:-1:1
          H(ii) = uicontrol('style','push','units','pix','position',[10 (ii-1)*80 150 60],...
              'string',varargin{ii},'fontsize',20,'callback',@select);
      end
      waitfor(hF)
      %Select and close:
      function select(src,~)
          idx = 1:n;
          selection = idx(ismember(H,src));
          close(hF)
          return
      end
  end

Save this is in mymenu.m
