Changing colour of title in plots

 Hello, I am trying to change the colour of strings in my plot titles and have used the following

title('\color{magenta}Month1, \color{cyan}Month2, \color{red}Month3')

However, I now want the strings Month1, Month2 & Month3 to be on different lines. I have tried

title({'\color{magenta}Month1, \color{cyan}Month2, \color{red}Month3'})

but the syntax is wrong.

Regards Jason

You simply need to tweak your existing title call. Put each as a separate string in a cell array:

title({'\color{magenta}Month1', '\color{cyan}Month2', '\color{red}Month3'})

This will do what you want.

sorry I forgot one minor detail, rather than the string literal, what if I want whats contained within folder and filename?

folder=get(handles.editFolderName,'String'); filename=get(handles.textName,'String'); Thanks

I would not call that detail ‘minor’.

What are the classes and dimensions of ‘folder’ and ‘filename’? Are they char arrays, string variables, elements of cell arrays, structures?

How do you want them displayed?

Jason’s ‘Answer’ moved here:

They are string properties of GUIDE edit boxes

Let’s try this again:

What are the classes and dimensions of ‘folder’ and ‘filename’?

Sorry I was away from computer. So when I do this:

t=get(handles.textSaveFolder,'String')
class(t)

I get

ans =

      'char'

No worries.

Since you want different colours for each line, the elements of the title argument need to be created in a loop:

t = {'Month1', 'Month2', 'Month3'};
c = {'magenta', 'cyan', 'red'};
for k1 = 1:numel(t)
    tc{k1} = sprintf('\\color{%s}%s', c{k1}, t{k1});
end
title(tc)

Experiment to get the result you want.

Im really sorry but I wwas mistaken, its still not working when I use a name for a string.

folder =

      'C:\images\BC_1.0um_1.6um (Cam530)'

its class is:

ans =

      'char'

So using the suggestion:

t = {folder, 'Month2', 'Month1'};
c = {'magenta', 'cyan', 'red'};
for k1 = 1:numel(t)
    tc{k1} = sprintf('\\color{%s}%s', c{k1}, t{k1});
end
title(tc)

I get:

The single ‘backslant’ (\) characters are causing the problem, and the underscore characters cause a problem with the interpreter. You need to add two additional strrep calls:

t = {'C:\images\BC_1.0um_1.6um (Cam530)', 'C:\images\BC_1.0um_1.6um (Cam531)', 'C:\images\BC_1.0um_1.6um (Cam532)'};
c = {'magenta', 'cyan', 'red'};
for k1 = 1:numel(t)
    ts = strrep(t{k1}, '\','\\');                           % Replace ‘\’ With ‘\\’
    ts = strrep(ts, '_','\_');                              % Replace ‘_’ With ‘\_’
    tc{k1} = sprintf('\\color{%s}%s', c{k1}, ts);
end
title(tc)

Single backslant operators are interpreted as control characters in sprintf (and fprintf), and underscores as designating the next character as a subscript using the default TeX interpreter. Putting a backslant ahead of such characters will force them to be treated as literals.

Specifying 'Interpreter','none' turns off everything, so none of the control characters are interpreted. Two serial strrep calls are necessary because it will replace one but not both in a single call. Doing both replacements in one call results in two different outputs, each with a different replacement but neither with both.

Use \newline.

title('\color{magenta}Month1,\newline \color{cyan}Month2,\newline \color{red}Month3')
