Stop CoP areas overlapping

It's confusing even if there are ways to explain it.

There's also a bug where the CoP isn't shown for the first few readings.

Here's an example where it's confusing because the CoP values are shown (and are overlapping) even though the heat pump isn't doing anything.

Here's an example where there's no CoP for the first few cycles even though the heat pump is doing something.

We're now using bars to make the CoP visualization less ambiguous. The smoothing is all done in the underlying values, not in the lines joining them up.

We also suppress the bars if there isn't a reasonable way to derive a CoP. Using bars copes nicely with a null entry.

The new calculation technique also means we get a CoP for the first few readings.

Ironically, in this case there were no readings from the system at 21:41 - 21:43 so the CoP is AWOL. It's a shame, but it's OK.

Note that the CoP figure stops at 21:47 because at 21:48 there was no output. The "smooshing" doesn't just spread it into the future.

The smoothing out takes into account values from the past and the future. This smooths out big jumps in CoP at the beginning and the end of cycles.

The more robust algorithm means we can leave the "max CoP" value as high as 7 rather than the old 5 which was just trying to bring some sanity to bear.

Here's another comparison of the old versus the new:
