[Gnuplot-info] plotting time series data

[Roderick S. <rod...@gm...>]

I’m new to gnuplot (love it!) but can’t work out how to plot time series data from a file when the file contains no time information, just equally-spaced data values.

I have a binary file which has one year’s worth of data at 1-minute intervals.

I can plot it using:

plot ‘2021.dat’ binary format=“%int32” using 0:1

But I want the X axis to be a date axis so I can, for example, set xrange.

How do I get the timestamps into the plot?

Thanks in advance.
