Hi,
I am trying to read column 4 and 10 from 12 excel files and plot 12 graphs from it but I am only getting plot 1. Below is the code can you guide me how to do it properly.
Code:
close all; clear all; clc;
% To access the folder
folder = fullfile('C:','Users','muhammad','Documents','PhD_3rdYr','Experiments_2021','performance_110');
files = dir( fullfile(folder, '*.ods') );
% Reading and extracting data from 12 excel files hence plotting
for ii = 1:length(12)
data = readmatrix(fullfile(files(ii).folder,files(ii).name), 'NumHeaderLines', 1)
x= data(:,10)
y=data(:,4)
figure(1)
% Plotting data
plot(x,y,'x','LineWidth',0.5);
hold on
%Spacing and griding
xlim([0 6])
ylim([0 0.8])
hold on
grid on
% Outlet starting
y = 0.237;
line ([0,5],[y,y],'color','r');
txt = {'Outlet,Invert Level = 237 mm'};
text(1,0.25,txt)
% Design Head
y = 0.737; %17 mm
line ([0,5],[y,y],'color','r');
txt = {'Design Head = 737 mm'};
text(1,0.76,txt)
% Design Limit Box
x =5;
line ([x,x],[0,0.737],'color','r')
hold on
%Chart Representation
title('Outlet-110 mm');
xlabel('flowrate (l/s)');
ylabel('Head (m))');
% legend('VFC');
end

hello
all plots are updated at each loop iteration on the same figure(1)
so at the end you have only one figure showing the last iteration
change in your code : figure(1) into figure(ii)
