Plot data to a certain date with array

Sorry I am new to coding! Apologies if this is a dumb question.

I a years worth of data and an array saying 1 when it is january and 0 when its not. I need to plot data only when its january, but im unsure how to work in the array into my plot.

Thanks!

Give this a try:

>> tt = timetable((1:365)','RowTimes',datetime(2021,1,1:365))
tt =
  365×1 timetable
       Time        Var1
    ___________    ____
    01-Jan-2021      1 
    02-Jan-2021      2 
    03-Jan-2021      3 
[snip]
    29-Dec-2021    363 
    30-Dec-2021    364 
    31-Dec-2021    365 
>> jan = tt.Time.Month == 1;
>> plot(tt.Time(jan),tt.Var1(jan))

this is similar to what i was thinking however the data is in increments of 10 minutes per day so theres over 5000 lines of data. I am unsure on how to plot the data when the array just equals on and not when it equals 0.

nvm did it by adding (plotindex) at the end of each data

IIUC, my "jan" variable was the same as your "plotindex".
