i'm getting time, t, as a char and need to make it so i can plot it in matlab

If you have received the time t as a character in MATLAB, you will first need to convert it into a format that MATLAB can understand for plotting. MATLAB works with datetime or numerical formats for time-based data.

Here's how you can convert a char time t into a datetime format in MATLAB:

main.m
% Assuming t is in the format of 'HH:MM:SS'
t_char = '12:30:45';  % Example char time
t_datetime = datetime(t_char, 'InputFormat', 'HH:mm:ss');
144 chars
4 lines

Once you have the time in datetime format, you can plot it against some numerical data using standard plot functions in MATLAB.

For example, if you have some function y = f(x) and you want to plot y against time t_datetime, you can do something like:

main.m
x = 1:0.1:10;  % Example numerical data
y = f(x);      % Example function

plot(t_datetime, y);
xlabel('Time');
ylabel('Y values');
title('Plot of Y values against Time');

Make sure to replace 'HH:mm:ss' with the actual format of your time characters.
