I want to plot multiple curves to a single plot in a for loop. My data is stored in tables within a cell array. How can I do this? Here is what I have so far.
%DSC Data Subtract Function adn Plotter
%This file was designed to read raw DSC data from a text file and then
%perform a series of operations then plot it.
clear,clc;
format long
[file,path] = uigetfile('*.txt*',...
'Select One or More Files (MUST BE TEXT FILE)', ...
'MultiSelect', 'on');
% opts = detectImportOptions("DSC Script\DSC_Test.txt");
% opts.DataLines = [3 5];
%Put code that if the size if a file isnt choosen that the program ends (If
%file or path = 0 then end code)
degsign = char(0176);
TableArray = cell(length(file),1);
fileID = zeros(length(file));
%Create if statement for the instance if the number of files is one
if path == 0
message = 'You did not make a valid selection or canceled the dialog box. Please rerun the code with the proper selection';
title = "ERROR!"
f = msgbox(message,title)
elseif ischar(file) == 0
for i = 1 : length(file)
FileName = file{i};
fileID(i,1) = fopen(FileName);
T = readtable(FileName,"PreserveVariableNames",true);%Creates table from the data in the text file
TNew = removevars(T,{'Var1'}); % Removes Var Colum from Data as it is unnecessary
TNew = rmmissing(TNew);%Removes NaN values from the table and now the data is prepared for use and manipulation.
HFlo = TNew{:,"Unsubtracted_2"} - TNew{:,"Baseline_2"};
WeightPercent = (TNew{:,"Unsubtracted"}./TNew{1,"Unsubtracted"}).*100;
TNew = addvars(TNew,HFlo,'Before','Heat Flow');
TNew = addvars(TNew,WeightPercent,'Before',"Unsubtracted");
TableArray{i} = TNew;
plot(TNew.Sample,TNew.HFlo)
title(FileName)
xlabel('Temperature °C' )
ylabel('Heat Flow mW/mg')
figure
plot(TNew.Sample,TNew.WeightPercent)
title(FileName)
xlabel('Temperature °C' )
ylabel('Weight %')
figure
end
elseif ischar(file) == 1
fileID = fopen(file);
T = readtable(file,"PreserveVariableNames",true);
TNew = removevars(T,{'Var1'});
TNew = rmmissing(TNew);
HFlo = TNew{:,"Unsubtracted_2"} - TNew{:,"Baseline_2"};
WeightPercent = (TNew{:,"Unsubtracted"}./TNew{1,"Unsubtracted"}).*100;
TNew = addvars(TNew,HFlo,'Before','Heat Flow');
TNew = addvars(TNew,WeightPercent,'Before',"Unsubtracted");
plot(TNew.Sample,TNew.HFlo)
title(FileName)
xlabel('Temperature °C' )
ylabel('Heat Flow mW/mg')
figure;
plot(TNew.Sample,TNew.WeightPercent)
title(FileName)
xlabel('Temperature °C' )
ylabel('Weight %')
end
Maybe I approached this problem initally wrong.
Thank you for you help!
