plot many variables from table

I have a 8760x2 table containing every hour of the year and a variable for each hour:

ta=[array2table(t) array2table(TIMVARDEN)];

It looks like this:

'15-Jan-2021 03:00:00' 0

'15-Jan-2021 04:00:00' 0

'15-Jan-2021 05:00:00' 0

'15-Jan-2021 06:00:00' 0

'15-Jan-2021 07:00:00' 0

'15-Jan-2021 08:00:00' 0

'15-Jan-2021 09:00:00' 0

'15-Jan-2021 10:00:00' 5.88000000000102

'15-Jan-2021 11:00:00' 171.240000000002

'15-Jan-2021 12:00:00' 0

'15-Jan-2021 13:00:00' 0

I want to make a plot or multiple plots that makes it clear when an hour has another value than zero.

Any ideas?

you can use this format to get the list in a month and you can sort i a table

def day_in_month(year,month):

if month>12 or month<1 :

return"invalid input"

months_days=[31,28,31,30,31,30,31,31,30,31,30,31]

if is_leap(year) and month==2 :

return 29

return months_days[month-1]

Could you please specify?

at the row:

return "invalid input"

I get :

Invalid use of operator.
