Good Morning,
I am trying to graph the attached .csv file but it does not run correctly, my code is as follows.
t,p = csvread('re.csv',1,0);
y_line_1= tmp(:,7);
x_line_1= tmp(:,3);
plot(x_line_1,y_line_1,'b-')
I appreciate the help.

csvread: The file can only contain numeric values.
I would prefer readtable command. With this command you have flexibility to use variety of import options too. This "opts" object contains properties that control the data import process.
For more info on readtable see the following link - readtable
tmp = readtable('re.csv');
y_line_1= table2array(tmp(:,7));
x_line_1= table2array(tmp(:,3));
plot(x_line_1,y_line_1,'b-')

I see this a lot:
table2array(tmp(:,7)) % extracts a sub table then converts it to an array
Which is a complicated way of doing:
tmp.(7) % directly extracts the seventh variable.
Also, in newer releases you could be using:
tmp = readmatrix('re.csv');

@Jeremy Hughes thanks for the suggestion :) I am looking forward for readmatrix command
