How to differentiate between each plot when every time I change the parameters from GUI, it updates same figure with new output?

I have designed one GUI for my technical analysis and comparison of process and controller output.Each time when I change the external parameters from GUI,I am getting same colour output(i.e blue)in same window.When I am comparing two or more outputs,it is becoming little confusing for me to analyse the performance. Is there any other way to segregate/differentiate one output from another?

You can mention color.

plot(x,y,'color','r') ; 'r','b','g' etc...

As it is inside gui, you may not mention color. You may use

plot(x,y,'color',rand(1,3))

Or:

C = {'r' 'b' 'g' 'y' 'm' 'k' 'c'} ;  % mention all colors here 
plot(x,y,'color',C{randsample(1:length(C),1)}) ; % select color randomly from C

Thanks KSSV its working now...but let me know if it is possible to add legends on right top corner??

[KSSV]

You have to make a legend cell every time inside the function. Means when you call the function, you must know how many it is called. Follow this analogy:

plot(rand(10,1),'color','r')
Legend{1}='first' ;
hold on
plot(rand(10,1),'color','b') 
Legend{2}='second';
legend(Legend);

Hello KSSV I used 'insert legend' from the figure options...thanks for your help.

C = {'r' 'b' 'g' 'y' 'm' 'k' 'c'} ;  % mention all colors here 
plot(x,y,'color',C{randsample(1:length(C),1)}) ; % select color randomly from C

this code I am using for plotting graaph. I have one more question KSSV, Can we select these colours in the same sequence as given in order C = {'r' 'b' 'g' 'y' 'm' 'k' 'c'} instead of using 'randsample'

Awaiting your response. Thank You.

That case, put a count how many times you are calling that function and use this count.
