How to separate 2 columns from a structure in MATLAB and save it into different variables(as a Matrix)

Hi and have a great time

I have some timetables as it appears in the picture and each timetable can be a structure.

I have 4 columns but I want to load the second column as X values and the transpose of 3rd columns as Y values and then plot X in terms of Y

How can I do it ? (I don't know how to separate the columns of a timetable)

Thanks for your answers

Please attach your data

[Raheel Naveed]

% Assuming the 'Id_6' variable is already loaded and contains the timetable data

% Access by names
Time_Data=Id_6.Time
X = Id_6.('Data:1');
Y = Id_6.('Data:2').'; % Transpose

plot(X, Y);

[Atefeh]

Unrecognized method, property, or field 'Data:1' for class 'timeseries'.

Error in work (line 7)

X = Id_6.('Data:1');

Thanks a bunch Raheel , But the mentioned error is appeared.

As requested above as well, please attach your data. Use the paperclip button to do so.

Please find enclosed the output.mat

I attached the output data and I really appreciate your time and considerations

"I have some timetables as it appears in the picture and each timetable can be a structure."

No, what you have are clearly TIMESERIES objects:

https://www.mathworks.com/help/matlab/time-series-objects.html

S = load('output.mat')

S = struct with fields:
        A: [1×1 timeseries]
     Bus4: [1×1 struct]
    Iabc0: [1×1 timeseries]
    Iabc1: [1×1 timeseries]
    Iabc2: [1×1 timeseries]
    Iabc3: [1×1 timeseries]
    Iabc4: [1×1 timeseries]
    Iabc5: [1×1 timeseries]
    Iabc6: [1×1 timeseries]
     Id_0: [1×1 timeseries]
     Id_1: [1×1 timeseries]
     Id_2: [1×1 timeseries]
     Id_3: [1×1 timeseries]
     Id_4: [1×1 timeseries]
     Id_5: [1×1 timeseries]
     Id_6: [1×1 timeseries]
    Vabc0: [1×1 timeseries]
    Vabc1: [1×1 timeseries]
    Vabc2: [1×1 timeseries]
    Vabc3: [1×1 timeseries]
    Vabc4: [1×1 timeseries]
    Vabc5: [1×1 timeseries]
    Vabc6: [1×1 timeseries]
     Vd_0: [1×1 timeseries]
     Vd_1: [1×1 timeseries]
     Vd_2: [1×1 timeseries]
     Vd_3: [1×1 timeseries]
     Vd_4: [1×1 timeseries]
     Vd_5: [1×1 timeseries]
     Vd_6: [1×1 timeseries]
     tout: [1000×1 double]

A = S.Id_6

  timeseries

  Common Properties:
            Name: ''
            Time: [3001x1 double]
        TimeInfo: tsdata.timemetadata
            Data: [3001x3 double]
        DataInfo: tsdata.datametadata

D = get(A,'Data')

D = 3001×3

Yes! It works.

I really appreciate your professional feedback.

Hello

I have an output file of my Simulink Model which is attached.

I want to plot a 3D model as a mfile based on Id_6 (column 1&2) and t

Can you advise?
