How to add legend of consicutive plots on the same graph?

For an example, I want to plot a graph with different t (t1, t2, t3 etc) using GUI. The plot will be done consecutively, meaning, once the plot for t1 completed it will wait for the second input value i.e. t2 and after getting input it will plot t2 along with t1 in the same graph. Now I want to differentiate them automatically to the graph by adding legends.

Could anybody please help me in that regards? Thanks in advance !
