Dear KL

Thank you, sir, for your kind help. But sir again I am facing one problem which is

legend_str{ii} = num2str(ii)

in this command, numbers are converted into strings and saved in 'legend_str{ii}'. But sir in my case I have to write theta1 theta2.. in symbolic form as shown in attach picture. How I do this sir.

When you add your legend, specify your interpreter as tex. For example,

legend_str{ii} = ['\theta_' num2str(ii)];
%%other commands
legend(legend_str,'location','NorthWest', 'interpreter', 'tex')

Dear Sir KL

I did the same coding as guided by your kind self. now I am facing another issue which is, after theta 9, the numbering style is not aligned as shown in the attached picture. from theta 10 to theta 24. how to align it sir. Please help me sir

[KL]

That's simple, use

 legend_str{ii} = ['\theta_{' num2str(ii) '}'];
