Generate time series plot on a 7-day rolling window from data in database tables SC_TwinBridge_stream and SC_TwinBridge_meteo.
SC_TwinBridge_stream.gp is a gnuplot recipe for plotting SC_TwinBridge_stream data from columns TmStamp, SW_Depth_m, and WaterTemp_C.
SC_TwinBridge_meteo.gp is recipe for plotting SC_TwinBridge_meteo data from columns TmStamp, AirTemp_C, Rel_Hum, and Rain_mm_Tot.
genplot.sh pulls CSV data from http://www.czo.psu.edu/SQL_Query3.php via form posting using curl. The resulting CSV data are then used by the above gnuplot recipes to produce PNG formatted images.
genplot.sh takes two optional arguments. This is quick and dirty so no real argument processing is performed at this time -- if argument 2 is needed, argument 1 is required.
Usage: genplot.sh [(program directory) output directory]
Program directory is the absolute or relative path to the genplot.sh program. This directory contains the GNUplot recipes.
Output directory is the directory where generated images are placed.
