Timeseries data in Matlab

Hi,

I have textfile .txt for temperature data over the past 50 years (attached as pic).

I want to plot it as timeseries data.

How can I do this?

What function should I use?

Thank you.

(Here is snippet of data. It goes on like this until year 2017).

(Smallest time unit is hour in 3 hour intervals)

(Temp is the dependent variable).

try it:

[filename,folder]=uigetfile('*.txt','please select your txt file');
a=readtable(fullfile(folder,filename));
time=datetime([a{:,2:5} zeros(size(a,1),2)]);
temp=a{:,6};
figure;
plot(time,temp)

Hello. It works but what is reason for this part? What does it do? Thank you.

...zeros(size(a,1),2)]);

[JESUS DAVID ARIZA ROYETH]

these zeros are the minutes and seconds that are set to 0 by default, please formally accept my answer.

Hello. Please, one more question, then I will accept your answer.

I loaded this .txt file into Matlab.

Now I want to do the same for this - make timeseries.

(Var6 = Temp)

Smallest unit of time is 1 hour.

Can you suggest correct function?

Thank you.
