Hello,
I am new to Matlab so forgive me if there is very basic question.
I have a matlab script that reads in, reformat and plot acceleration time series.
I would like to overlay two accelerations series in the same graph.
Please see the code below:
function accelPlot()
% plot acceleration time history and response spectra
close all
% load recorded nodal data
acc = load('/home/kowal/OpenSeesPy/SiteResponseAnalysis_layeredColumn/accelerationNS.out');
time = acc(:,1);
% remove time column from data
acc(:,1) = [];
% data descriptors
[nStep, nAcc] = size(acc);
nDOF = 2;
nNode = nAcc/nDOF;
% reshape data
a = reshape(acc, nStep, nDOF, nNode)/9.81;
% plot horizontal acceleration time history at ground surface
figure(1)
plot(time, a(:,1,nNode), '-b','linewidth',1.5)
grid on
box on
xlabel('time (sec)','fontsize',16)
ylabel('acceleration (g)','fontsize',16)
set(gca,'fontsize',14)
print -depsc2 surfaceAccel.eps
I would be really grateful for your help.
Thanks!

Hi,
You can use the command 'hold on' after your first plot command to have the plot overlay.
Example:
plot(x,y)
hold on
plot(w,z)
Regards
