Freezing line

[nitrx]

I knew the freezing line was giving problems but in v1.9.1 (954) it doesn't show up ?

[daj]

Same here

I just installed 1.9.1 last night so overnight was the first chance for it to dip towards zero, and no line appeared.

I've had to change the way the freezing line is drawn in 1.9.1 because the chart component changed. One thing that I have tried to fix as a result is the line being drawn off the chart, and I did a quick test with some random data which seemed to show it was all working, but perhaps in Cumulus itself it doesn't; I have no easy way of testing it in real conditions. I'll have a look at the code.

Do either of you have any of the chart lines turned off? Is it not working on both the temp chart and the daily min/max/avg chart?

[nitrx]

I've turned the freezing line on in cumulus. Last night is was almost freezing the charts go to minus two in both the graphs and also in cumulus and on the web, but there's no freezing line in cumulus or on the web, I'm almost sure it's going to freeze in the coming night (sunday to monday) but had expected to see the freezing line this morning.

I've found the bug. The min/max/avg chart one works OK, but there's a silly mistake in my code for the temp chart. Fixed in next build.

Great

Excellent

I can confirm, for me at least, the freeze/zero line has reappeared in the latest build (955)

Thanks steve, I missed it.

But a small problem: in the picture below, the "apparent temperature" falls outside the scale for the temperature graph (was -6.9 at the time)

That's strange, that works fine for me:

Cumulus relies on the chart component to auto-scale the axes; I can't think why it isn't doing it in your case. I'll check the settings - perhaps I have accidentally set a maximum range - it looks like both of us have a range of around 20 degrees.

Stopped and restarted Cumulus, and now the graph looks OK:

Don't like the way apparent temp is consistantly lower than windchill ....

You need to speak to the Australian Bureau of Meteorology about that.

I edited my data to increase the range, and it still plots OK:

I think it's just another bug in the chart component

Stopped and restarted Cumulus, and now the graph looks OK

Sorry, I missed this post. Let's hope it was just a one-off glitch.
