i need to plot timestamped data from a file in matlab

To plot timestamped data from a file in MATLAB, you can follow these steps:

1. Read the data from the file into MATLAB using readmatrix or readtable functions.

2. Convert the timestamp columns into MATLAB datetime format using the datetime function.

3. Plot the data using the plot function, specifying the datetime data as the x-axis.

Here is some example code:

main.m
% read the data from file
data = readmatrix('data_file.csv');

% convert timestamp columns to datetime
timestamp = datetime(data(:, 1:6));

% plot the data
plot(timestamp, data(:, 7));
185 chars
9 lines

In this example, the data is read from a CSV file using readmatrix. The first six columns contain the timestamp data, which is converted to MATLAB datetime format using the datetime function. The seventh column contains the data that you want to plot. Finally, the plot function is used to create the plot, with the datetime data as the x-axis and the data to be plotted as the y-axis.
