I want to plot the graph of data having hour at 8:00 clock. I have been trying to do this from past few days.

I have attached the CSV file as well. Please suggest me how can I plot the graph.

[Scott MacKenzie]

No CSV file was attached. And you might want to clarify what you mean by "having hour at 8:00 o'clock". Perhaps even attach a mock-up of the sort of graph you are aiming for

[Eric Sofen]

Read the data in as a timetable, You can pull out all the data where the hour is 8 by doing:

tt8 = tt(tt.Time.hour == 8, :)

Then plot by doing something like this:

plot(tt8.Time, tt8.Data)

Thankyou for your reply. It really helped me.
