I have a text file containing of a continuous signal 2 columns :

I want to plot 5 seconds

close all
data3=readtable ('PLETH.txt');
Date_Time = data3(:,1);
datecell=table2array(Date_Time);
load = data3(:,2);
A = table2array(load)

Hi,

You don't need to convert the table into array.

A simple

plot(data3.x, data3.y);

should work.

Here, x and y are your column labels.

This

plot(data3(:,1), data3(:,2));

should also work just fine.

Refer to Access Data in a Table for more details.

I get this error.

Also, I want to plot only 5 seconds of the data.

Error in ppg (line 5)

plot(data3(:,1), data3(:,2))

Could you put up the complete code and the data file here?

It's difficult to debug without all the information.
