Agree that if you are using the WeeWX plot engine you have to archive the data you wish to plot; however, if you use something other than the WeeWX plot engine to render your plots then you can avoid archiving the data. I played around with a sun position plot routine in some php a few years ago to produce a graphic file showing a plot of solar altitude through the day with the current sun position highlighted. Whilst the details escape me (whilst I had it working I never actually deployed it) I believe I used WeeWX to produce a report with time and solar altitude data for the day. This report was produced one per day at midnight for the coming day. The php routine then read this data and generated the plot. A similar thing could be done with a json format data file and highcharts or some other plot library.
Developing the report will take a little thought, It could be done with some inline python code in a template or via a SLE to do the hard work and a basic template (SLE would probably be a little easier to deal with setting up pyephem). The report timing option provides the means to control when the report is produced. Gary -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
