Hello all,
I am trying to plot a data of multiple plots in a single graph. I am facing a problem in plotting it. I need the data from different Y axis in a single axis bar i.e, im my case it is from -200:200. And for X axis I need a scale for each and every X axis data as the data varies for every Y axis data. Along with that I need to plot the data with an offset at different location and i also need the offset distance as a scale either on top or on bottom X axis. I have tried plotting it but I am unable to retrive the desired result. Can someone please help me. My code is:
Z = readtable('Atq100_2.xlsx') ;
data = table2array(Z) ;
plot(data(:,2)+10, data(:,1),'linewidth', 2);
hold on
plot(data(:,4)+250, data(:,3),'linewidth', 2);
hold on
plot(data(:,6)+500, data(:,5),'linewidth', 2);
hold on
plot(data(:,8)+1000, data(:,7),'linewidth', 2);
hold on
plot(data(:,10)+1500, data(:,9),'linewidth', 2);
hold off
legend('x=10mm', 'x=250mm', 'x=500mm', 'x=1000mm', 'x=1500mm', 'Location', 'northeastoutside');

One option is to use the subplot function in a loop —
data = table2array(Z) ;
plot(data(:,2)+10, data(:,1),'linewidth', 2);
hold on
plot(data(:,4)+250, data(:,3),'linewidth', 2);
hold on
plot(data(:,6)+500, data(:,5),'linewidth', 2);
hold on
plot(data(:,8)+1000, data(:,7),'linewidth', 2);
hold on
plot(data(:,10)+1500, data(:,9),'linewidth', 2);
hold off
legend('x=10mm', 'x=250mm', 'x=500mm', 'x=1000mm', 'x=1500mm', 'Location', 'northeastoutside');
N = size(data,2);
Nsp = N/2;
ttlc = {'x=10mm', 'x=250mm', 'x=500mm', 'x=1000mm', 'x=1500mm'};
figure
for k = 1:Nsp
subplot(1,Nsp,k)
col = [2 1]+2*(k-1);
plot(data(:,col(1)), data(:,col(2)), 'LineWidth',2)
grid
title(ttlc{k})
ylim([-1 1]*200)
end
I am not certain what the desired result is.

Thank you so much. It looks more like the desired result i need. I am glad and thankful for your help.
