How do I fix my legend?

I am trying to create a legend key that says the name of a cell, then is followed by the value for mutual information.

Something like this:

legend(strcat('T9C11, MI =' num2str(mutualInfoTotal(67)),'T8C7','T8C5','T9C6')

But with the values for mutual information after each of the electrode names. But what I am doing now isn't working. So, what I want the legend to be like is like:

T9C11, MI = ______

T8C7, MI = ______

and so on.

Thanks!

What is the error you are getting?

Also, if you are plotting different datasets at once, using strcat will not work for seperating the legend names.

Looping throught your data is an easy way (though not too efficient) to create the titles.

baseNames = {'T9C11','T8C7','T8C5','T9C6'};
for idx = 1:length(baseNames)
    NewNames{idx} = sprintf('%s, MI = %2.2f',baseNames{idx},mutualInfoTotal(idx)) % whatever value mutualInfoTotal you need here
end
legend(NewNames)

edit: forgot to store the values into the array! Thanks, Tommy.

Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other
syntax error. To construct matrices, use brackets instead of parentheses.

what is the full error, and is it only erroring when you try to add the legend?

Okay, the code you suggested won't work because the mutual information that I want to pull from is under a different variable than T9C11 (i.e., it is mutualInfoTotal(67))

You can still use the same idea, just pull the pertinent values from mutualInfoTotal:

baseNames = {'T9C11','T8C7','T8C5','T9C6'};
baseValues = mutualInfoTotal([67 68 69 70]); % or whatever the indices are
NewNames = cell(numel(baseNames,1));
for idx = 1:length(baseNames)
    NewNames{idx} = sprintf('%s, MI = %2.2f',baseNames{idx},baseValues(idx));
end
legend(NewNames)

(One slight addition - storing the strings in a cell array.)

@Tommy, you should probably move this to the answer section.

You can still use the same idea as Ruger28's comment, just pull the pertinent values from mutualInfoTotal:

baseNames = {'T9C11','T8C7','T8C5','T9C6'};
baseValues = mutualInfoTotal([67 68 69 70]); % or whatever the indices are
NewNames = cell(numel(baseNames,1));
for idx = 1:length(baseNames)
    NewNames{idx} = sprintf('%s, MI = %2.2f',baseNames{idx},baseValues(idx));
end
legend(NewNames)
