First Col to Rep Date in Double Array

I have a beginner question.

I have an array of doubles where columns from 2 to 10 stores doubles.

But I need the first column to represent time, so I can plot them against whichever double series I need to.

I don't know exactly how to get around with this.

I have the dates in serial numbers, but when I plot them against other double series, the x-axis obviously shows numbers instead of something like 11/1/2019.

How can I solve this issue??

Convert the serial number column to datetime. plot is datetime-aware; you'll get a time axis automagically. The deprecated datenum requires using the klunky datetick function to draw the time axes; not recommended for the faint of heart.

I am trying to store this into a matrix, and my matrix is in doubles. How can I resolve this issue?

[Turlough Hughes]

As in a serial number from excel? Can you attach some of the data?

Hey Turlough, I resolved this in plot as the plot command makes the datetick possible to be adjusted. Thanks guys!

Hi,

You can use timetable array which associates a time with each row and then plot them against date and time using stackedplot.

Refer the following links for more information on these functions: https://www.mathworks.com/help/matlab/ref/timetable.html, https://www.mathworks.com/help/matlab/ref/stackedplot.html
