Plot time series of two set of data

The attached is two set of data with different size, 'ARMOR', and 'HadGEM2', respectively. I would be grateful if someone could help me to plot the time series of these two sets of data on one frame, so that the x-axis specifies the time based on the year or year and month and the y-axis value of object 'temperature'. Thanks

Your variables are timeseries, so you should just be able to plot them.

load ARMOR_anomaly.mat
Armor

  timeseries

  Common Properties:
            Name: 'unnamed'
            Time: [20x1 double]
        TimeInfo: tsdata.timemetadata
            Data: [20x1 double]
        DataInfo: tsdata.datametadata

plot(Armor)

It sounds like you are saying that time data incorporated into your time series is incorrect?

Armor.Time

ans = 20×1

0 1 2 3 4 5 6 7 8 9

There is a separate time timeseries in your mat file as well. Since Time there is also just index number, I assume we should look at Data instead.

time.Data

ans = 20×1

464196 472956 481740 490500 499260 508020 516804 525564 534324 543084

Perhaps you can help us out by explaining how you created time.Data? Or where it was captured from? Is it perhaps posixtime?

datetime(time.Data,'ConvertFrom','posixtime')

ans = 20×1 datetime array

   08-Jan-1970 04:46:36
   08-Jan-1970 07:12:36

You should probably either correct your timeseries variables so the correct time and data are in a single series, or not use the timeseries data type at all.

hello

I started this , but I am unsure about how the dates / time is coded in your data (as I discovered , HadGEM2 has to do with Mid-Pliocene era so this is certainly not what I have now :

load('ARMOR_anomaly.mat')
xdate1 = datetime(datevec(time.Data))

xdate1 = 20×1 datetime array
   03-Dec-1270
   27-Nov-1294

data1 = (Armor.Data);
figure(1),plot(xdate1,data1,'-*',"DatetimeTickFormat","yyyy-MM");

load('HadGEM2_anomaly.mat')
xdate2 = datetime(datevec(time.Data))

xdate2 = 28×1 datetime array

time range supposed to be 1993 to 2021

[Mathieu NOE]

I don't understand how your time data is formated

you can always for ce the time axis to match your range

your two data sets do have different length - do they both cover the same range , or is only the longest one covering the 1993 to 2021 range (and they would have the same time spacing ?)
