This works:

[d,s,r] = xlsread('temp.csv');

t = d(:,1);
v = d(:,2);

figure(1)
plot(t, v);
grid
xlabel('Time')
ylabel('Value')

I have used this set of commands.However the x-axis shows double no. but not time information(HH:MM:SS), how could I show the time information in the graph?

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.
