Title in maths symbol and title as legend on each plot on different locations.

Please:

1. How can I make a title as legend on each of my plot on the different location apart from the general title?
2. How can I print the greek letter "xi" as maths symbol. I tried title(sprintf('L = %i, \xi = %i', L(i), xi(i))) but couldn't work. Is giving me "\xi" insteads of the maths symbol ξ. I also wants the 0.02 to appear as it is not -2.000000e-02.

%% initialization
clear 
clc
close all
%% Set up the data (just enough to need a large legend and to show variety)
t = linspace(0, 1, 11);
x = linspace(0, 1, 100)';
L = [6 2 3 7];
xi = [0, -0.02, -0.2, -0.5];
%% Start plotting
% Use an extra two plots spaces in subplot where the legend will go
figind = [1 2 4 5]; % locations where we actually want to plot data
figure(1)
for i=1:length(L)
    subplot(2, 3, figind(i))
    A = xi(i) ./ (1 + exp(-xi(i)*t.*x)); % the data to plot
    plot(x, A)
    
    xlabel('x')
    ylabel('y')
    title(sprintf('L = %i, \xi = %i', L(i), xi(i)))
end

Thank you for this. Please how can make the legend for t to appear at the bottom or top?

I don't understand what it is you are asking for.
