How to set numbers in legend

I'm using this code to set the numbers in the legend, see attached file.

This is what happens

legend( sprintf('%g\n', vars))

What is your goal? What do you want to put in the legend as a name? Your current code looks like you want to put the contents of your vector as the name in the legend. Because that is a very long list, you only see a single item in the legend.

I would like to link the ID number of a plotline in a legend. In my plot above i only have a few lines.

Then you should provide the ID of the line, not the data itself. What is the content of vars? Try to make a self-contained example so we can fix your code instead of guessing what you did and trying to fix that.

if map < 10

elseif map > 09 
filelocation_mat = [path,num2str(map),'_rf.mat'];
filelocation_csv = [path,num2str(map),'_rf.csv'];


end
