Cumulus Trend Graph Cleanup

[tjaliwalpa]

I have been using Cumulus for a few months now. My website has been active for just over a month now. I have noticed something interesting with the trend graphs. It happens with Wind Speed, Wind Direction and to a certain degree with Temperature.

The graphs produced can be rahter ragged near the current time (right of the graph image), but with time Cumulus seems to smooth out graph and remove the busy plotting into a more general curve. In other words, as the curve progresses to the left, the business of the plot is corrected to become more readable and regular.

I've attached two examples. You will see on the right that the speed graph is rather busy, but the left is quite neat. The other example (Direction) is not the best example I have seen, but you will notice the plotting is less intense on the left than on the far right. Often, the Wind direction plots are busy near the right and all over the place, but these are removed and the Average direction plots remain, with eronious plots removed as they pass, over time, to the left of the graph.

Has anyone else experienced the observations I have made? If this is a function of Cumulus, I have not read about it before. These are not criticisms, just the opposite.

It's the difference between plotting data 'live', once a minute, and 'pre-loading' the graphs with data at start up from the data logs and/or station logger, at whatever logging interval you have Cumulus and/or your station set to. It looks like you started Cumulus up just after 20:00.

That explains it. Actually, I have Cumulus restart 3 times each day because of an issue I had with losing my Internet connection when I had the computer running 24 x 7. I fixed this by restarting my computer at just after 4:05, 12:05 and 20:05. I probably could have gotten away with 2 restarts, but made it 3 just to be on the safe side.
