Plot from cell array
显示 更早的评论
I want to plot data from cell array. I tried many ways, and I can't get it. I used plot inside and outside the loop, also scatter and stackedplot.
clc; clear variables; close all;
% Pregunta 01
filename='Test_Specimen_2.txt';
D = readtable('Test_Specimen_2.txt',...
'Range','A10:AN76',...
'ReadVariableNames',true);
i=1;
while i<=size(D,2)/2
d1 = D(:,2*i);
d2 = D(:,2*i-1);
D1{i} = [d1 d2];
i=i+1;
end
i=1;
while i<= size(D1,2)
stackedplot(D1{i},{'STRAIN','STRESS'});
hold on
i=i+1;
end

It looks like you're trying to create a stackedplot with 2 lines per axes which is demonstrated here:
Instead of grouping columns of data in cell arrays, you just need to group the variable names together. It appears you want the lines to be grouped as [Var2, Var1], [Var4, Var3], [Var6, Var5], etc. Here's how to achieve that with stackedplot.
D = array2table(rand(10,8)); % demo table
varPairs = [D.Properties.VariableNames(2:2:end)', ...
D.Properties.VariableNames(1:2:end)'];
pairedVars = arrayfun(@(r){varPairs{r,:}},1:size(varPairs,1),'UniformOutput',false)'; %#ok<CCAT1>
stackedplot(D,pairedVars)
