It displays intermediate values for me (with my Fine Offset)?

I must be out of date then.

I was sure, but now I think about it was the sectors not the pointer. I should keep quiet about something that I very rarely look at any more, shut away on my laptop server on top of a filing cabinet.

"Note also that the gauge component only seems to display to integer values."

Why? Is it not possible to plot intermediate values after the data has been factored in?

Sorry Barry I was wrong, it does.

Mark,

See what you mean but, there is something very strange going on here. The wind speed that Cumulus plots is an average. This is displayed on the desktop panel clearly. So, why should Cumulus calculate and plot the average wind speed to the nearest integer without the 'Round wind speeds' box being ticked in Configuration/Station settings.
Help file...
Round wind speeds
Tick this to have wind speeds rounded to the nearest integer

Surely it is capable of calculating an average to one decimal place and plotting that.

Barry

It is, and it does if you tell it to, but that is of course spurious accuracy. But your average is presumably coming from the weather station as you haven't configured Cumulus to calculate it.

I don't understand you Steve. If Cumulus calculates an average from values supplied by Davis and then plots them, how can they be spurious? They are a true representation of an average of what Davis sends to Cumulus.
To set this up does it just require the checking of "Calculate 10 minute wind average" on station Settings, or are there other functions needed to be checked

If you calculate an average from data that is accurate to 1 mph, and you give the average figure using decimal places, then you are implying an accuracy in the original data which does not exist.

Yes.
