6 years of output data

With September coming to an end, another 12 months of data is complete to illustrate how my Powerspout has performed.  Happily, it has been a good year with total energy generated as good as the best of the previous years.
Below are three plots showing:

  1. output on a day to day basis between October of one year and September of the following year, covering the past 6 years
  2. cumulative output through the same 12 month period for the past 6 years
  3. the total number of days in each 12 month period that a given output was achieved, also for the past 6 years
In each plot, the 2018-19 year is represented by a black line and previous years by coloured lines.
