RTMC: plotting max value

AMK Aug 1, 2012 04:57 PM

Hi,
I am adding wind speed data to a plot and would like to plot just the max value recorded for each day - instead of what's being logged (max value every 10 minutes). Is there a way to do this?

Select Data: "station:110.WINDS_10M_MAX"

Thanks,
AMK

Take a look at MaxRunOverTime in the RTMC help. As an example:

(MaxRunOverTime("Server:CR200Series_2.Public.WindSpeed_ms",Timestamp("Server:CR200Series_2.Public.WindSpeed_ms"),nsecPerDay))

Returns the maximum of the WindSpeed_ms variable since midnight (midnight designated by the nsecperday constant). In this example (which I run for my "home" weather station), the datalogger is called CR200Series_2, Public table, Windspeed_ms variable.

Looks like the syntax may have been cut off (at least when viewed in my browser). Maybe this is better...

(MaxRunOverTime("Server:CR200Series_2.Public.WindSpeed_ms",
Timestamp("Server:CR200Series_2.Public.WindSpeed_ms"),nsecPerDay))
