This part is relatively straightforward. Using your data example, you can do the following:
* table #+name: measurements | Date | PSA | | |------------+-----+---------| | 2017-08-11 | 185 | | | 2017-08-21 | | #ffdd99 | | 2017-09-19 | 854 | #ffdd99 | #+begin_src gnuplot :var data=measurements :file timeseries.pdf :results file set xdata time set timefmt "%Y-%m-%d" set xrange ["2017-08-01":"2017-10-01"] unset key plot data using 1:2 with histeps #+end_src #+results: [[file:timeseries.pdf]]
The colouring bit is harder and I don't know whether it's possible or not. I suggest you look at examples on the web, e.g. http://gnuplot.sourceforge.net/demo/ to see if anything fits what you are trying to do. HTH, eric -- : Eric S Fraga via Emacs 27.0.50, Org release_9.1.1-78-gfbf47c
