MATLAB: How to make the plot count by ones so that I have grid markers and numbers at each integer.

Question

My plot goes from time t=0 to t=15 on the x axis, but it's counting by 5's and I want it to count by ones so that all numbers are labeled and graph lines appear for every number on the time axis.

Answer 1

See if this does what you want:

x = linspace(0, 15,250);
y = sin(2*pi*x/10).*sin(5*pi*x/10);
figure(1)
plot(x, y)
grid
xt = get(gca, 'XTick')                          % Find Existing X-Ticks
xtix = min(xt) : max(xt);                       % Define New X-Ticks
set(gca, 'XTick',xtix)                          % Set New X-Tick Values
