Identifying a line in multiple plots

I have code that plots all of my data as random colours and it works perfectly.
for t = 1:20
tempY = Sim_Graphs_Y{t,1};
txt = [num2str(t)];
plot(NewX,tempY,'Color',rand(1,3),'LineStyle','--','DisplayName',txt);
hold on
end
plot(NewX,ygraph1,'Color','r','LineStyle','-','DisplayName','Exp');
legend
savefig('weightingTEST.fig')
Is there a better way for me to be able to work out which line is which outside of just trying to match the colour as best i can?

I made the app attached with App Designer. You could make a similar app to help you identify the selected lines. You can change the lines within the startup function.

Not sure what that means. You can set a breakpoint on the plot line and see each curve right when it's plotted.
If you want you can, with sprintf(), create a cell array of strings inside the loop that describes the parameters of each curve and then give that cell array to legend()

Ahh i probably explained that badly, i just want i would like to know which line is the one closest to the solid red line. And i was wondering if there was a better way for me to be able to see which line that is outside of trying to match the colour of the line to the colour in the legend.

Not sure what "closed" means. To find the closest, compute the mean absolute deviation. There is a function mad
or
theMAD(t) = mean(abs(curve - redCurve));
and look for the min value
[minMad, indexOfMinMad] = min(theMAD)
