Subscript indices must either be real positive integers or logicals while using plot function

figure(1)
%time_north_sec=1x111 double
%Q_north_cut_off=111x111 double
plot(time_north_sec,Q_north_cut_off(:,1)*1e6)
xlabel('Lag (second)','FontWeight', 'bold')
ylabel('autocovariance function (mm^2)','FontWeight', 'bold')
title('North Autocovariance Function')
set(gca, 'fontsize', 16, 'fontweight', 'bold');
ylim = get(gca,'YLim');
ylim([31, 0]);
After running the code I get "Subscript indices must either be real positive integers or logicals while using plot function" although the plot seems OK.

If you are not able to see your plot, try to play with ylim()....mention the ranges min first and then max.
