plot column x until a specific row

I am asking user to import multiple data such as:.txt and .csv file. Since I am piloting true stress vs true strain, after the breaking point true strain value drops. what i want is to plot stain data till the max point(i don't want the strain data once it is broken). How to approach this problem? ex:1,696327,1.715222,1.724002,0.148660,0.08183,0.06558( stop at 1.724002). Any help would be much appreciated.

s = [1.696327,1.715222,1.724002,0.148660,0.08183,0.06558];
%%get maximum value
[val,idx] = max(s) ;

plot(s(1:idx))
