Within a legend, how do I modify where the text is relative to the symbol?

If you put a subscript within your text string in a legend, it lowers the symbol or line to the left of the text. For example, in the following code:

figure(1)
x = -10:0.1:10;
y = x.^2;
j=plot(x,y,'k-');
axis([-10 10 -2 110]);
legend('T_{experiment}')

Here, the black line to the left of "T_experiment" is at the bottom of the "T", and I would like it centered on the "T". I have tried adding an empty superscript to raise the symbol, but superscripts do not alter the symbol position. Is there a way to solve this problem?

Thanks!!

That's what _ do, use two _ _

legend('T__{experiment}')

Do I understand correctly: The problem is not the sub-scripting in the TeX string, but the relative position to the the symbol of the line style?

Then you could try to modify the text properties manually:

[legend_h, object_h] = legend(...)
text_h = findobj(object_h, 'flat', 'type', 'text');  % Does this work?
% Alternatively:
% typeList = get(object_h, 'Type');
% text_h   = object_h(strcmpi(typeList, 'text'));
set(text_h, 'VerticalAlignment', 'baseline');   % Or 'middle'

Seeing this question is still active, here is what worked for me (Matlab R2022a).

Instead of modifying the legend properties, I put the legend entries in latex form and set the interpreter to Latex as in the first line of code.

The resulting "math font" is italics. To have the legend in normal face, I used 'mathrm' as in the second line of code

legend('$T_{experiment}$', 'Interpreter', 'Latex')

legend('$\mathrm{T_{experiment}}$', 'Interpreter', 'Latex')
