Adjusting the legend spacing

I have slightly lengthy legend titles as shown in the figure below. Is there a way to adjust the location of 'a val' / 'b val' more towards the centre of their title name (move leftwards)?

Similarly for 'c limit' /'d limit' ( move towards right!!)

The sample code used to generate the plot is given below

a=rand(1,10);
b=rand(1,10);
c=ones(1,10)*0.7;
d=ones(1,10)*0.2;

figure;
p1=plot(a,'o-r');
hold on
p2=plot(b,'s-b');
p3=plot(c,'-.k');
p4=plot(d,'-.k');
lg=legend([p1 p2 p3 p4],'a val','b val','c limit','d limit');
lg.NumColumns=2;
title(lg,'raw data values from experiments          limitation values');
ylim([0 1.2])

I don't know of any way in the legend() function. You might try creating strings for your legends manually and put a \n at the end of the string or beginning of the string.

Alternatively make your own legend manually with the text() function and place them wherever you want.

Not directly answering your question, but a different (and more conventional) approach would be to move the limit annotations out of the legend.

rng default

a=rand(1,10);
b=rand(1,10);

figure
hold on
p1=plot(a,'o-r');
p2=plot(b,'s-b');
yline(0.7,'-.')
yline(0.2,'-.')
text(9,0.675,'d limit')
text(9,0.175,'c limit')

lg=legend([p1 p2],{'a','b'});
title('raw data values from experiments');
ylim([0 1.2])

Thanks alot @the cyclist for you effort. I am aware of this method.

I am particularly looking for ways to adjust the legend locations.
