Included w/ the wxgraphs are 'last 60min' (updated via clientrawextra-every 1min or so) and 'last hour' (clientrawhour updated :59min or whenever you set clientrawhour from the default). I think the time code for the 'last hour' script, 10-20-30,etc, are hard times.
The 60min graphs are temp, windspd, wind dir, and rain.
The last whole hour graphs are temp, windspd, wind dir, baro, solar, humidity, and rain.
I'm not sure what Stuart/jmcmurry others are using for x-axis time code for 60min graphs while getting temp, windspd, wind dir, baro, solar, humidity, and rain.
