How to create a plot for multiple CSV files in a loop?
Show older comments
I have 24 CSV files and for each of them I'd like to create a figure with 6 subplots (ie 24 figures each with 6 subplots) . The subplots are just one column of the csv files plotted against the first column (time). I'd like to use a loop to do this so it can be done automatically. The first 12 rows of the csv files need to be ignored.
I have tried using
csvFiles = dir("*.csv");
N = length(csvFiles);
for i = 1:N
fid = fopen('csvFiles(i)')
data = txtscan(fid,'Delimiter',',','Headerlines',12)
but txtscan is not recognised.
I have also tried using
fid = fopen('csvFiles(i)')
data = csvread(csvFiles(i).name,'Headerlines','12')
followed by
C0 = data(:,1);
C1 = data(:,2);
C2 = data(:,3);
C3 = data(:,4);
C4 = data(:,5);
C5 = data(:,6);
C6 = data(:,7);
subplot(6,1,1)
plot(C0, C1)
hold on
subplot(6,1,2)
plot(C0, C2)
hold on
subplot(6,1,3)
plot(C0, C3)
hold on
subplot(6,1,4)
plot(C0, C4)
hold on
subplot(6,1,5)
plot(C0, C5)
hold on
subplot(6,1,6)
plot(C0, C6)
hold on
But this has also not worked.

Better use readmatrix instead of csvread
