Hi all,
I have a signal (attached) over which I would like to plot mutiple vertical lines using x values (see image below)
x = [1648;2871;4022;6216;7327;8416]
My approach below:
can you help please?
load 'signal'
figure;
plot(cop_x_l); hold on
xline([x], repmat(ylim',1,size(x,2)), '--r')
Error using xline (line 29)
Passing multiple values to ConstantLine is not supported.

The ability to create multiple vertical or horizontal lines by passing a vector of values into the xline or yline functions was introduced in release R2021a. For earlier releases you'll need to call xline or yline once per value (perhaps in a for loop.)

Try this
x = [1,2,3,4,5]; % x interval
% load signal instead of data below
z = linspace(0,6,100);
y = exp(z);
plot(z,y);
xline(x,'-r');

Hi!
Try this
sig = rand(1,10000) ;
x = [1648 2871 4022 6216 7327 8416] ;
figure
plot(sig);
hold on
xline(x, '--r')
Hope this helps
