This works:
[d,s,r] = xlsread('temp.csv');
t = d(:,1);
v = d(:,2);
figure(1)
plot(t, v);
grid
xlabel('Time')
ylabel('Value')

You didn’t say you wanted it in that format. Use the datetick function:
[d,s,r] = xlsread('temp.csv');
t = d(:,1);
v = d(:,2);
figure(1)
plot(t, v);
grid
datetick('x', 'HH:MM:SS')
xlabel('Time')
ylabel('Value')
This should give you the plot you want.
