Focus plot and apply correct tick labels

Good Evening Everyone,

I'd much rather be asking you about Bayesian analysis over this, but unfortunately, I am terrible with MATLAB plots (not due to a lack of effort though).

I have a plot attached. It contains 1739 days of data. I need to do the following three things:

Focus in on the plot so that the y axis limits are -1 and 1 (right now they are -4 and 14). I'm uninterested in any values beyond these limits. Re-label the y axis from -1 to 1 in .10 increments. Re-label the x axis so that it starts with 1, ends with 1739, and has enough points in between that it is still readable. I've studied gca, datetick, ax=gca, etc. but I cannot accomplish any of these tasks without messing up the plot.

I am gracious for any assistance provided.

Look at this example

t=0:0.1:10
y=8*rand(size(t))-4
plot(t,y)
ylim([-1 1])
xl=xlim
nt=8  % number of ticks
xt=linspace(xl(1),xl(2),nt)
set(gca,'xtick',xt)
