2. Use aggregate type 'last'. It will return the last non-null value. For example, > > > <p>The last measured sea temperature is $day.seaTemperature.last at > $day.seaTemperature.lasttime</p> > > You don't want to use $latest.seaTemperature because that would give you > seaTemperature in the last record of the database, which is likely to be > null. > pond.txt for reading 60 minutes and remove it at 9:18. No data is > available for reading until new data is read > > Thanks! I am glad to confirm .last does perfectly what I mistakenly tried to achieve with latest.
I have adjusted my program to provide the sea temp only when new measurement is available, so by tomorrow, I should have few separate rare data points to play with. Doing that, I recalled I am already adding hourly temperature at this other location, I added it to the plot. Plot connects hourly temp points well. I just do not like square form of hourly data so I am off looking how to make lines connecting data points round :) Progress is made :) Many thanks for the nudge in the right direction! -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
