Legend symbol overbar

Hi,

I am trying to include a single letter with an 'over-bar' after the percentage sign in the following code for a legend on a plot:

legend('CG = 33.46%','string2' )

If anyone has an idea of how to do this, then that would be really great.

Thanks,

Robbie

plot(1:10)
h = legend('$$\overline{x}$$')
set(h,'Interpreter','latex','fontsize',24)

Hi, Thanks for your response. I can get this working but I can't get it 'embedded' within another string. I want something of the form 'string' followed by the x 'over-bar' in the legend. I get an error of the form:

Warning: Unable to interpret TeX string

Any suggestions?

Thanks,

Robbie

Like this?

h = legend(['before ','$$\overline{x}$$',' after'])
set(h,'Interpreter','latex','fontsize',24)

After more than five years, I had the same problem and I found your answer very useful. Thnak you very much! Carlo

I have a related question.

I am generating some plots where the symbol 'x' changes in the legend depending on what I am plotting. For one figure I have a string that defined symbol = '\omega_r^*'. How can I put an overbar over that instead of x?

Thanks

symbol = '\omega_r^*';
h = legend(['before ','$$\overline{',symbol,'}$$',' after'])
set(h,'Interpreter','latex','fontsize',24)

Notice that the general technique here is to take a series of characters and concatenate them -- where one (or more) of the character arrays is predefined in a variable.

When I do that I like to build up from a completely manual version of the character, like ...

s = 'I am a character array'; % Nothing special
s = ['I am a character array']; % Concatenating, but no variables yet
s = ['I am a ','character array']; % Split the character array
s = ['I am a ','character',' array']; % Split again

and then finally

c = 'character';
s = ['I am a ',c,' array']; % Insert one portion from a variable

Hello, the cyclist. I have a question too. I want to insert $\mathbf{\overline{Nu_{s}}}$ inside sprintf{' ') to get an overline on Nu. I am getting the error as Warning: Escaped character '\m' is not valid. See 'doc sprintf' for supported special characters

Any help would be appreciated. Thank you
