Hi everyone,
I want to plot dates that are expressed in the following format:
% x-axis
Time = [730211, 730241, 730302, 730333]
% y -axis
Values = [0.602300789014034, 0.603937673632081, 0.606134076857801, 0.609570252971655]
plot(Time,Values) % ERROR
I am not sure how to transform the existing time format into proper time format that can be used in a plot.
Thank you.

When I run those three lines of code I do not receive an error. Can you show the full and exact text of the error message you received (all the text displayed in red?)

Try this:
plot(Time,Values)
datetick('x','yyyy/mm/dd')
Experiment to get the result you want.
You can also transform them to a datetime (link) object, which is likely easier.
