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??
