legend for graphs by while loop

how to make a legend for the plot generated by the below code (this is an example code)

the legend look like (plot # , for ca = k)

figure();

hold on

k = 1e-3;

while ( k <=1.0 )

ca = k;

j = 1.0;

while (j > 1e-10)

while (condition) >= abs(1e-5)*j)

[T, H] = ode45(XXX);

end

j = j * 1e-1;

end

plot(T, H(:,1))

xlim([0 15])

end

k = k*10.0;

end

You can add legend in the plot command or use the legend function as mentioned in the documentation. Please follow the documentation given here https://in.mathworks.com/help/matlab/creating_plots/add-legend-to-graph.html

In order to help you better please share the entire code to view the generated figure

I know how to make a legend, but not for a graph generated by while loop

could you elaborate more using my example

Look at the examples at the doc for legend -- there's nothing different about whether mutiple lines were added with a for...end loop or manually.

Just try something...
