How to read and plot a txt file

I have this text file with time stamps and with values that I am trying to plot. I am not well versed in MatLab to even begin writing a code.

Answer 1

filename = 'Data1.txt';

T = readtable(filename)

T = 73×2 table
        Var1         Var2  
    ____________    _______

    11:26:42.028    -178.39
    11:26:42.126      175.5
    11:26:42.265    -170.07
    11:26:42.345    -172.13
    11:26:42.428     179.11
    11:26:42.526      179.7
    11:26:42.629     177.88
    11:26:42.759      169.8
    11:26:42.849     161.06
    11:26:42.945    -177.34
    11:26:43.068    -170.62
    11:26:43.146    -172.11
    11:26:43.278    -177.71
    11:26:43.362     173.86
    11:26:43.451     168.34
    11:26:43.555     170.14

plot(T.(1),T.(2))

Okay great! this worked! But I tried using this same code for a different file and I got an error.

Error using plot

Invalid data argument.

Error in AccelerometerGraph (line 3)

plot(T.(1),T.(2))

Wait nevermind, I forgot to edit it and delete the arrows, Thank you!!

You're welcome!

You can avoid deleting the arrows from the text file, if that's more convenient. The file is read just fine by readtable, so all you have to do is plot with the 3rd column instead of the 2nd:

filename = 'Data2.txt';

T = readtable(filename)

T = 86×3 table
        Var1         Var2      Var3  
    ____________    ______    _______

    10:18:28.544    {'->'}    -170.58
    10:18:28.672    {'->'}    -155.68
    10:18:28.761    {'->'}    -173.08
    10:18:28.863    {'->'}     178.71
    10:18:28.949    {'->'}     174.53
    10:18:29.093    {'->'}     169.34
    10:18:29.184    {'->'}      169.8
    10:18:29.277    {'->'}     170.72
    10:18:29.375    {'->'}     173.62
    10:18:29.458    {'->'}     177.41
    10:18:29.596    {'->'}    -178.71
    10:18:29.680    {'->'}    -172.09
    10:18:29.797    {'->'}    -170.26
    10:18:29.899    {'->'}    -171.57
    10:18:29.981    {'->'}     -170.6
    10:18:30.078    {'->'}    -176.27

plot(T.(1),T.(3)) % plot third column vs first column
