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.
