Change from 2022 to 2021 Plotting Issues

I have this code that is not quite finished yet, however it works on version 2022. Had to change to 2021 for licensing reasons and now it will not plot. HELP!

I was able to work through it! Thanks everyone!

Answer 2

[Steven Lord]

The ability to plot table arrays by passing them as inputs to the plot function was introduced in release R2022a as stated in the Release Notes. In an older release follow the suggestion in the error message and either use the stackedplot function to extract the data from the table array and pass the extracted data into plot.

To plot a table or a timetable, use the stackedplot function. As an alternative, extract table or timetable variables using dot or brace subscripting, and then pass the variables as input arguments to the plot function.

Thanks for the reply! I did start the process of reading the .txt file and MatLab reads all 3 columns in. How do I only plot column 1 and 3 now? My shortned altered code is below:

% This code takes RAW SE data, turns the files into text (.txt) files and
% then combines the HIGH, MID, and LOW frequency into one text file which
% can be then multi-selected and those selected files will be put onto a
% plot.

% Enter the directory to search
directory = uigetdir('*',"Select Folder With Files To Be Processed");

% List all items in the folder
fileList = dir(directory);

% Delete the subfolders from the list (i.e. only keep files)
fileList(vertcat(fileList.isdir)) = [];

figure

% Uses folder as title of plot
[ParentFolderPath] = fullfile(directory);
[~, ParentFolderName] = fileparts(ParentFolderPath);
title(ParentFolderName,'FontSize',20);

% Loop through each file, copy it and give new extension: .txt
for i = 1:numel(fileList)
    file = fullfile(directory, fileList(i).name);
    [tempDir, tempFile] = fileparts(file);
    status = copyfile(file, fullfile(tempDir, [tempFile, '.txt']));
end

% Combine HORIZONTAL text files

%location = input("location of test point: ","s");
fileName = "HORZ NOM.txt";

dL = dir(fullfile(directory,'*HLF*NOM.txt'));
dM = dir(fullfile(directory,'*HMF*NOM.txt'));
dH = dir(fullfile(directory,'*HHF*NOM.txt'));

for i = 1:numel(inf)

  tD = readtable(fullfile(dL(i).folder,dL(i).name),'numheaderlines',6,'readvariablenames',1);
  tD = [tD;readtable(fullfile(dM(i).folder,dM(i).name),'numheaderlines',6,'readvariablenames',1)];
  tD = [tD;readtable(fullfile(dH(i).folder,dH(i).name),'numheaderlines',6,'readvariablenames',1)];
  
  % do whatever with each set here before going on...
  writetable(tD,fullfile(directory, fileName));

  R = readtable(fileName)

  stackedplot(R,"Frequency","SE","Color",'Blue',LineWidth=1.5)

end

grid on

% Changing colors based on alphebetic order
newcolors = {'Blue','Red','#72a75b','#999999','#0003ff'};
colororder(newcolors);

% Sets pass/fail line
PFx = [10000 10000000 1000000000];
PFy = [20 80 80];

% Adds pass/fail line to plot
plot(PFx,PFy,'Color','Green','LineWidth',1.5);

% Changes legend location and removes pass/fail line from legend

Index into the table. Let's take a sample table.

load patients
p = table(LastName, Age, Weight);
head(p)

      LastName      Age    Weight
    ____________    ___    ______

    {'Smith'   }    38      176  
    {'Johnson' }    43      163  
    {'Williams'}    38      131  
    {'Jones'   }    40      133  
    {'Brown'   }    49      119  
    {'Davis'   }    46      142  
    {'Miller'  }    33      142  
    {'Wilson'  }    40      180  

Now create a stacked plot with just the Age and Weight variables.

stackedplot(p(:, [2 3]))

I ended up making it work. I realized how to use "." when reading tables which I had not needed to ever do before (still fairly new and was using the newer version). Thanks for your time though!
