Plotting leaving empty space before line begins

So this plot has a gap before the beginning of the line. I have checked the arrays being inputted and they have the correct values and therefore there should be no gap.

My current theory is based on the bottom and that when the program plots the points it is rounding the axis numbers and therefore not centering the graph at the start of the line.

Any ideas on how to fix this?

Yes, by default MATLAB will attempt to set the ticks at round numbers. If you prefer to have the limits exactly match your data, use axis tight

x = rand(1,5);
y = rand(1,5);
tiledlayout(1,2)
nexttile
plot(x,y)
title('Normal')

nexttile
plot(x,y)
title('axis tight')
axis tight

Thanks! I am just glad that it is not a problem with my arrays but something that matlab does automatically.
