plot when x variables are "strings"

I have created a following csv file

Column 1 "EST 9AM (PST 6AM)", "EST 10AM (PST 7AM)",...

Column 2 Temperature at these time

I read the file in Matlab and tried to plot them. But the error message is that "Error Using Plots: Invalid Data Argument."

You've got to change the data type to datetime. First fecht the date column with this:

T = readtable(filename)

then change it to datetime to any format that you need. like:

T.LocalTime.Format = 'MM/dd/uuuu HH:mm:ss'

you find additional information on the documentation of datetime here: https://de.mathworks.com/help/matlab/ref/datetime.html

Thank you. That would be my question. I read "EST 9AM (PST 6AM)",... from csv. How can one convert it to datetime format?
