MATLAB: Plot

Question

Hi everybody!

I am trying to plot a time series using the following code:

figure(1)
subplot(2, 2, 1);plot(buy_side(4, :));
xlim([-384 2520]); ylim([0 1]);
title('BUY SIDE');
set(gca,'YTick',[0, 0.5, 1],'XGrid','on','XTickLabel',{'Jan', 'Feb', 'Mar', 'Apr'},'XTick',[360 1057 1800 2520],'FontWeight','bold','FontSize','16');

but everytime I run this, there is an error:

Error using set
  Value must be numeric

Could you please give me a hint on what the error could be?

Thank you!
