overlaying 2 plot in one graph

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)
