Heating Degree Days Graph
Posted: Sun Dec 19, 2010 3:04 pm
Hi,
I have been playing with the graphing facilities and have come up with a graph that plots monthly HDD15 (Heating Degree Days, for a base temp of 15°C) totals over 3 years, based on daily average temperatures.
Addition: The graph definitions were developed from the "_tempdays-1year" example that Boris kindly provides as standard. Thanks for the head start, Boris.
N.B. As we are close to the sea my lowest temp band is "-2°C_or_less", but the general idea can easily be extended, and I've included (but commeted out) what I hope are suitable colours (gradually getting bluer) for another 6 bands if desired.
The reason I placed the average temperature line first (i.e. sensor 0) was to make it easier to extend the graph to colder temperature bands, this does mean that the temp line is sometimes "behind" but transparency allows it to be visible enough for me at least.
Maybe other will find this useful or at least interesting.
While developing the above I also found the following useful, it is similar but without the factors, so it shows the number of days in each band and was useful to reveal a couple of annomalies in my data where data was missing (the total number of days for each month should match the number of days in the month).
N.B. With this one, if you add extra colder bands, you'll also need to move (or remove) the average temperature line.
