Hi Gary. I did not get to try your suggestions until today. We went on a 3 week cruise, but when I got home I ended up with Covid. Not a very bad case, but I am just now getting my act together. Just a few comments: 1. I made your suggested change by commenting out the lines pertaining to wind gust, but I want to wait until I see a full days plot before making any other changes. One thing I do see is that the 1 Hour Average Speed is showing as dots rather than a continuous line as before. Does that mean the LineGap fraction has to be changed? 2. Regarding the windspeed v windgust differences you mention. I have a Peet Bros Ultimeter, so the windspeed (along with the other parameters) is emitted nearly constantly. My archive interval is 2 minutes, while the Loops are approx every 2 seconds. I noticed that when I had windgust included in the plot, it appeared to more accurately reflect the "High Wind" reading under "Since Midnight" on the Current Conditions page. Is it possible to have windgust plotted while having the chart label as windspeed?
I just want to say thank you for all the help you have given me over the past few years...it is greatly appreciated On Monday, June 6, 2022 at 9:45:57 PM UTC-4 gjr80 wrote: > Steve, > > So have you tried: > > # time_length = 43200 > > # Changed color and data_type > [[[[wind_avg]]]] > color = 'yellow' > data_type = windSpeed > aggregate_type = avg > aggregate_interval = 3600 # 1 Hour > line_gap_fraction = 0.05 > label = 1 Hour Avg Speed > # End of addition > [[[[windSpeed]]]] > color = 0x000000 > anti_alias = 2 > > That will plot windSpeed (black) and the one hour average windSpeed > (yellow) values.
