I'm using python on a Pi to log movement detected by a Infrared sensor. I'd like to represent the data on a line/bar graph with time on the x axis and the y axis being binary to represent movemnet (1) or no movement (0).

Each movement will be recorded as a new row on the log (csv) file.

Here is an example of the data:

Start Date,Start Time, End Date, End Time, Duration
2017-11-02,19:45:20,2017-11-02,19:45:59,0:00:38
2017-11-02,22:26:53,2017-11-02,22:27:50,0:00:56
2017-11-03,01:09:49,2017-11-03,01:10:31,0:00:42
2017-11-03,01:23:23,2017-11-03,01:23:43,0:00:20
2017-11-03,04:24:10,2017-11-03,04:33:03,0:08:52

The monitoring is daily within a defined window (7pm to 7am) and a separate log file is created for each logging window.

I would like my graph to represent the entire period of 7pm to 7am.

Is it possible for gnuplot to represent a graph to my requirements without the need to modify the existing input file? My fear is that I may need to create a new input file specifically for gnuplot where each minute is recorded as a new row in the file with either 1 or 0 to show movement during that minute.

I'm new to gnuplot so any advice would be appreciated.
